1. Mr. Holloway is a craftsman who makes custom guitars by hand. His last order was for 2 guitars, and it took him 8 weeks to make them. He receives an order to make 7 guitars. If he makes the guitars at the same rate, how long will it take Mr. Holloway to make the guitars?
a=28
b=7
c=4
d=35
2. Solve for x : 4 x - 7 = 49
a=12
b=56
c=14
d=28
3. Michael ordered a chicken parm sandwich for $8, Xavier and Daniel both got a meatball sub for $7.75, and Tony got a veal parm for $9. Tony just got paid so he said the meal was on him as long as his friends took care of the tip. If they left an 18% tip how much would each of Tony's friends pay if they split it evenly?
a=$32.50
b=$5.85
c=$38.35
d=$1.95
4. Simplify: 5 * (10 * 6 + 9) - 9
a=345
b=336
c=291
d=741

1) 28 weeks or A

2) 14 or c

Step-by-step explanation:

1) 8/2= 4

   4 multiplied by 7 = 28

answer is 28

2) 4x-7=49

        add 7 to both sides

    4x=49+7

     4x=56

         divide 56 by 4

    56/4=12

answer is 12

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
