Question

Dan uses 340 grams of blueberries to make 24 fluid ounces of smoothie. last week he made 54 fluid ounces of smoothie. how many grams of blueberries did dan use last week?

Answer 1

Answer: He used 765 grams of blueberries.

Explanation:

The quantity of blueberries is directly proportional to the quantity of smoothie.

Equation of direct variation :
`(x_1)/(y_1)=(x_2)/(y_2)`

Substitute
`x_1=340\text{ grams},\ \ \ y_1=24\text{ fluid ounces}`

`y_2=54\text{ fluid ounces}`

To find :
`x_2`

`(340)/(24)=(x_2)/(54)`

`\Rightarrow\ x_2=(340)/(24)*54\\\\\Rightarrow\ x_2=765`

Hence, he used 765 grams of blueberries.
