A person receives a paycheck of d dollars. The person spends 18% of the paycheck on rent, 15% of the paycheck on insurance, and 22% of the paycheck

on food and puts the remainder of the paycheck into savings.

If the amount the person puts into savings can be

represented by the

expression d - 0.18d - 0.15d - 0.22d, which expression also represents the

amount the person puts into savings?

O 0.45d

O 0.550

O 1.450

O 1.550

0.45d

Step-by-step explanation:

Given that :

Amount of paycheck = d

Amount spent on rent = 18%

Amount spent on insurance = 15%

Amount spent on food = 22%

Amount put into savings = d - 0.18d - 0.15d - 0.22d

Amount put into savings = d - ( 0.18d + 0.15d + 0.22d)

d - 0.55d

Amount put into savings = 0.45d

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

the radius is 2 times the diameter.
