If savings are represented by 45° on a circle graph showing all expenses, and the total expenses are $1440, how much go into savings?

Select one:

a. $240

b. $120

c. $180

d. $300

Answer 1

$180 go into savings

Explanation:

Given : Savings are represented by 45° on a circle graph showing all expenses.

Total expenses are $1440

To Find : How much go into savings?

Solution:

Total angle of expense = 360°

Savings =
`\frac{\text{Saving angle}}{\text{Total angle}} * 1440`

=
`(45)/(360) * 1440`

=
`180`

Hence $180 go into savings
