Question

Lydia uses 15 grams of protein powder to make a 22-ounce shake. She decides to make shakes for the week and plans to make 198 ounces. How many grams of protein powder will Lydia use for the entire week?

Answer 1

We have been given that Lydia uses 15 grams of protein powder to make a 22-ounce shake. She decides to make shakes for the week and plans to make 198 ounces. We are asked to find the grams of protein powder Lydia will use.

We will use proportions to solve our given problem.

`\frac{\text{Amount of protein powder}}{\text{Amount of shake}}=\frac{15\text{grams}}{22\text{ ounces}}`

`\frac{\text{Amount of protein powder}}{\text{198 ounces}}=\frac{15\text{grams}}{22\text{ ounces}}`

`\frac{\text{Amount of protein powder}}{\text{198 ounces}}* \text{198 ounces}=\frac{15\text{grams}}{22\text{ ounces}}* \text{198 ounces}`

`\text{Amount of protein powder}=15\text{grams}* 9`

`\text{Amount of protein powder}=135\text{ grams}`

Therefore, Lydia will use 135 grams of protein powder for the entire week.
