Question

The chart below shows how many cups of lemonade Marcia sold each hour she had her lemonade stand set up. To make 10 cups of lemonade, Marcia has to squeeze 3 lemons. How many lemons did Marcia use in the first 4 hours?

Answer 1

Answer:

$123\frac{1}{3}\ cups$

Step-by-step explanation:

Given

$10\ cups = 3\ lemons$

See attachment for chart

Required:

Lemons used in first 4 hours

First, we calculate the number of lemon sold in the first 4 hours.

$Lemon = 6 + 5 + 11 + 15$

$Lemon= 37$

Represent the number of cups of lemonades needed with x

So, we have:

$x = 37\ lemons$

and

$10\ cups = 3\ lemons$

Cross Multiply:

$x * 3 = 10 * 37$

$3x = 370$

Make x the subject

$\frac{3x}{3} = \frac{370}{3}$

$x = \frac{370}{3}$

$x = 123\frac{1}{3}$ cups
