Answer:

63 grams of protein in 9 ounces of tuna.

Step-by-step explanation:

Equivalent ratios are a rule of three problem.

In this problem, we have that:

3 ounce serving of tuna provides 21 grams of protein. To find the equivalent ratio, how many grams of protein are there in one ounce serving of tuna?

3 ounces - 21 grams

1 ounce - x grams

3x = 21

x = 7

The ratio is 7 grams of protein per ounce, so 7:1.

So in 9 ounces of tuna, there are 9*7 = 63 grams of protein.

If the price of a cd that normally costs $17.50 was marked up by 8% what is the new cost
Nana76 [90]
CD cost=17.50
Marked up=8%
So 8%of 17.50
8÷100×17.50=1.4
So add the old cd cost to the answer
=17.50+1.4=18.9 is the new cost
