Question

Oliver read for 450 minutes this month. His goal is to read for 10% more minutes next month. If Oliver meets his goal,how many minutes will he read in all during the two months

Answer 1

Oliver will read 945 minutes in 2 months.

Explanation:

Given:

Number of minutes read this month = 450 mins

Percent of minutes to read next month = 10%

We need to find the number of minutes he read in two months.

Solution:

First we will find the number of minutes he read in next month.

number of minutes he read in next month is equal to Number of minutes read this month plus Percent of minutes to read next month multiplied by Number of minutes read this month.

framing in equation form we get;

number of minutes he read in next month =
`450+(10)/(100)* 450 =450+45 =495\ mins`

Now number of minutes he read in two months is equal to sum of Number of minutes read this month and number of minutes he read in next month.

framing in equation form we get;

number of minutes he read in two months =
`450+495 = 945\ mins`

Hence Oliver will read 945 minutes in 2 months.

Answer 2

Oliver read in two months = 945 minutes

Explanation:

Oliver read in this month = 450 minutes

Goal for the next month = 10 % more than this month =
`(110)/(100)` × 450

⇒ Oliver read in next month = 495 minute

⇒ Oliver total read in two months = 450 + 495 = 945 minutes

Thus Oliver read in two months = 945 minutes
