252 dollars. (First you find how much is being added each week, it’s 24 dollars, then you multiply it by 18, and get 252.)
Answer:
x=2
Step-by-step explanation:
7x - 3 = 11
Add 3 to each side
7x - 3+3 = 11+3
7x = 14
Divide by 7
7x/7 = 14/7
x = 2
This is a simple problem with some quick addition and subtraction, and a bit of multiplication.
First we figure out how much money you're spending in total, which is $300 each year, for 20 years, so 300 x 20 = 6,000. Now, since the problem is asking for a maximum amount for percentage rate, this means we find the 9% for all 20 years combined and not individually. 9% of 6,000 is of course 540, so if we subtract 540 from 6,000, we get 5,460.
This means your answer is $5,460
