Please help! This is due tomorrow and I really need help worth 20 and i'll mark brainliest! Kelly runs a lemonade stand at the park. The table shows the
profit she earns for different numbers of cups of lemonade sold.
Cups sold Profit ($)
15 1.75
21 4.75
27 7.75
30 9.25
45 16.75
a. What price does Kelly charge for each cup of lemonade?

b. How many cups must Kelly sell in order to make a profit?

c. Write the equation that shows the amount of profit, p, for n number of
cups sold.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
