Answer:
Jennifer paid $108
Step-by-step explanation:
First you have to figure out how much Jennifer's parents paid. In order to do that you will have to do:
180 * 40 = 7,200 Then do: 7,200 / 100 which is 72 OR YOU CAN:
40 / 100 = .40 Then do : .40 * 72 which is 72
So Jennifer's parents paid $72.
So now you figured out how much Jennifer's parents paid, so to figure out how much Jennifer paid do:
180 - 72 which is $108.
This is how you know how much did Jennifer pay.

The answer to this is 15 because you would multiply 5*3 to get you answer or you could do 5+5+5 either way it equals 15
If we let Q be the number of quarters and N be number of nickels, this is the formula we would use:
[1] 25Q + 5N = 635 (using cents instead of dollars)
We also know something about Q and N.
[2] Q + N = 51
So multiply both sides of the second equation by 5. The reason we do this is because we're going to need to cancel out one of the variables (either Q or N) to solve for the other one. If we multiply times 5, we'll have 5N in both equations.
5Q + 5N = 255
Now we have two equations, and the second one can be subtracted from the first.
25Q + 5N = 635
-(5Q + 5N) = -255
---------------------
20Q = 380
so
Q = 19
There are 19 quarters.
And since there are 51 coins in all, 51-19 = 32 nickels.
