1) packet contains 750 grams plus 20% extra cereal.
750 grams is 100%. Add 20% = 120%
750 grams * 120% = 900 grams total.

2) Jenny's salary 27,500. Salary increased by 3%.
27,500 is 100%. Add 3% increase = 103%
27,500 x 103% = 28,325 new salary

3) Old ticket price 77. Price increased by 11%
77 is 100%. Add 11% increase = 111%
77 x 111% = 85.47 new ticket price

4) Original price 795. Price reduction 12%
795 is 100%. Deduct 12% reduction = 88%
795 x 88% = 699.60 new price

5) Car battery cost 58. plus VAT at 17 1/2%
58 is 100%. Add 17 1/2 % = 117 1/2%
58 x 117 1/2% = 68.15 Total bill

6) telephone bill 66. plus VAT at 17 1/2%
66 is 100%. Add 17 1/2 %
66 x 117 1/2% = 77.55 total bill

7) Lisa investment 3500. Interest rate 3.5%. term 1 year.
S.I. = 3,500 x 3.5% x 1year
S.I. = 122.50 interest for the year
Total amount at year-end = 3500 + 122.50 = 3,622.50

8) Principal = 2500, interest rate = 4% , term = 3 years.
Needed total value after one year.
S.I. = 2500 x 4% x 1 year
S.I. = 100 interest for the year.
Total value after one year = 2500 + 100 = 2600

9) Value of car = 9000, depreciation rate = 10%
9000 is 100%, less depreciation 10% = 90%
9000 x 90% = 8100 end of year value

10) normal price 1.85. reduced by 25%
1.85 is 100% less 25% = 75%
1.85 x 75% = 1.3875 rounded to 1.39

11) Normal price is 100%, reduced by 15%. Sales price is 85%
a) drill: 60 x 85% = 51.00
b) lawnmower: 190 x 85% = 161.50
c) tin of paint: 12 x 85% = 10.20

a) one student is chosen from classroom a, then a student is chosen from classroom b.

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b. this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes. this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes. this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes. this makes them dependent events.

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).
