Question

Dashawn started to monitor how many calories he consumed during breakfast and lunch. 55% of his calories came from his breakfast. He consumed 718 calories during lunch How many total calories did he consume from both meals? Round your answer to the nearest tenth.

Answer 1

The total calories consumed from both meals = 1595.6 calories

Explanation:

Given:

Dashawn had 55% of his calories from his breakfast.

He consumed 718 calories during lunch

To find the total calories he consumed from lunch and breakfast.

Solution:

Dashawn is monitoring his calories for breakfast and lunch only.

So, if he consumes 55% calories during breakfast, then percentage of calories he consumes during lunch =
`100-55=45\%`

Let total calories he consumes from both meals be =
`x`

Thus, calories he consumes during lunch can be given as :

⇒
`45\%\ of\ x`

⇒
`(45)/(100) * x`

⇒
`0.45 * x`

⇒
`0.45x`

We know that calories taken during lunch = 718.

So, we have,

`0.45x=718`

Solving for
`x`

Dividing bot sides by 0.45

`(0.45x)/(0.45)=(718)/(0.45)`

`x=1595.55\approx 1595.6`

Thus, the total calories consumed from both meals = 1595.6 calories
