Numerical Answers Expected!

Answer 1

@Snapbacklive How far have you gotten with this problem so far? Where are you getting stuck with it?

Answer 2

We can set this up as an equation. Let T be the total cost, and M be the number of months she's lived there. Then T = 750M + 1415.

We have that she's paid $8165 so far, so plug that in for T and solve for M.

Answer 3

so T= 8,165 + 750M

Answer 4

@Snapbacklive T is the total cost paid after M months.

You're trying to find out: "How many months has she lived in her apartment if she has paid $8,165? "


In other words, solve 8,165 = 750*M + 1415 for "M".

Do you understand why this is the desired equation? (It's ok to be confused, no worries).

Answer 5

So 10 ?

Answer 7

@Snapbacklive how did you obtain the value of 10? Did you graph it? Did you guess & check? Did you solve it algebraically?

Answer 8

i used a calculator

Answer 9

can u please me on this other question please.

Answer 10

What does 10 represent? Also what specific steps did you take on your calculator? It's difficult to give help if I don't know what you're doing, mathematically.

Answer 11

i just put 750 times 10.888 but it was wrong

Answer 12

Here's a step-by-step on how to solve 8,165 = 750*M + 1415 for "M"

Step one:
8,165 = 750*M + 1415 now subtract 1415 from both sides and what do you get?

Answer 13

it's about 11 months

Answer 14

Depends on how you define "about". I mean, 11 months is closer than say 140 months... ;-p But ok.

8,165 = 750*M + 1415 subtract 1415 from both sides...
6,750 = 750*M now divide both sides by 750

Answer 15

now can u please help me on this other question please.
