Answer:

7 Months

Step-by-step explanation:

x=number of months

how much is deducted total=number of months times amount deducted per m onth

amount deducted per month=45

number of months=x

how much deducted total=45x

460-deducted total is more than 100

460-45x>100

solve for x

add 45x to both sides

460>100+45x

subtract 100

360>45x

divide both sides by 45

8>x

answer is 7 months

if he does 8 months, then he will have exatly 100 and 100 is noe more than 100

Answer:

7 Months

Step-by-step explanation

You have to multiply each answer by 45, and subtract each answer from 460. The one that gives you more than 100 is your answer. The answer is 7 months, if he wants to have more than 100 dollars. The answer is 8 months if he wants to have 100 dollars.
