Question

a box of cereal states that there are 75 calories in a 3/4 serving what is the unit rate for calories cup how many calories are there in 2 cups

Answer 1

We know that a box of cereal states that there are 75 calories in a 3/4 cup.

To find the unit rate for calories cup we must represent the the situation with an equation

`\frac{75\text{ calories}}{(3)/(4)\text{ cup}}=\frac{x\text{ calories}}{1\text{ cup}}`

Then, to find the unit rate for calories we need to solve the equation for x

`x\text{ calories}=\frac{75\text{ calories}\cdot1\text{ cup}}{(3)/(4)\text{ cup}}=100\text{ calories}`

Now, to find how many calories there are in 2 cups we must multiply the unit rate for calories by 2

`x\text{ calories=100 calories}\cdot2=200\text{ calories}`

Finally, the answers are:

- The unit rate for calories is 100 calories/cup.

- In 2 cups there are 200 calories.
