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.
