Chapter 7: Q 451 (page 738)

Rachel had a 21-ounce strawberry shake that has 739 calories. How many calories are there in a32-ounce shake?

Short Answer

Expert verified

32-ounce shake will have 1126.09 calories.

Step by step solution

01

Step 1. Given information

21-ounce strawberry shake has 739-calories.

02

Step 2. Solution

Let x-calories in a 32-ounce shake.

if a 21-ounce strawberry shake has 739-calories, how many calories will be there in31-ounce shake?

Translate into a proportion.

$\frac{o u n c e}{c a l o r i e s} = \frac{o u n c e}{c a l o r i e s}$

$\frac{21}{739} = \frac{32}{x}$

Multiply both sides by LCD, $739 x$

$(739 x) (\frac{21}{739}) = (739 x) (\frac{32}{x}) 21 x = 739 \times 32 x = \frac{23648}{21} x = 1126.09$
