Problem

Osvoldo has a goal of getting at least $30\%$30, percent of his grams of carbohydrates each day from whole grains. Today, he ate $220$220 grams of carbohydrates, and $55$55 grams were from whole grains.

Did Osvoldo meet his goal? Why?

, Osvoldo ate 

 grams of whole grains 

 than his goal.

Hint #11 / 5

To find the number of grams in Osvoldo's goal, multiply the percent by the total grams of carbohydrates.

$\blueD{30\%} \times \greenD{220} = \text{?}$start color #11accd, 30, percent, end color #11accd, times, start color #1fab54, 220, end color #1fab54, equals, start text, question mark, end text

Hint #22 / 5

Percent means per hundred, so $\blueD{30\%}$start color #11accd, 30, percent, end color #11accd is equivalent to $\blueD{\dfrac{30}{100}}$start color #11accd, start fraction, 30, divided by, 100, end fraction, end color #11accd which is also equal to $\blueD{30\div 100}$start color #11accd, 30, divided by, 100, end color #11accd.

$\blueD{30 \div 100 = 0.3}$start color #11accd, 30, divided by, 100, equals, 0, point, 3, end color #11accd

Hint #33 / 5

Now we can find the number of grams of whole grains for Osvoldo's goal.

$\blueD{0.3} \times \greenD{220}=66$start color #11accd, 0, point, 3, end color #11accd, times, start color #1fab54, 220, end color #1fab54, equals, 66

Osvoldo had a goal of eating $66$66 grams of whole grains.

Hint #44 / 5

Osvoldo had a goal of eating $66$66 grams of whole grains, but he only ate $\maroonD{55}$start color #ca337c, 55, end color #ca337c grams.

$66-\maroonD{55}=11$66, minus, start color #ca337c, 55, end color #ca337c, equals, 11

Hint #55 / 5

No, Osvoldo ate $11$11 grams of whole grains less than his goal.
