I cant understand the question
So Colin is required to pay $300 for 15 total months in order to get his credit card balance down to $0.
In order to find this total, we need to take the amount he is going to pay per month ($300) and multiply is by the total number of months that he is going to be paying that amount (15):
$300 * 15 months = $4,500
The total amount of money that he is going to pay after his card balance reaches $0 is $4,500.
However, Colin only maxed out his credit card to $4,000 - the rest of the money is due to interest. So to find this amount, we take the total amount that he paid ($4,500) and subtract it from the total amount he initially maxed out his card with ($4,000):
$4,500 - $4,000 = $500
The amount of interest that Colin has paid when his credit card balance is $0 is $500.
The line y=7 is a horizontal line with a slope of 0.
Slope intercept form of
y=mx+b
would be
y-y1=m(x-x1)
m=0 and point of (-1,-10)
y-(-10)=0
y=-10
First you would want to find the original price. to do this you need to find the multiple.
1) start with 100
if it's an increase, add
if it's a decrease, subtract
in this case we want to add to find the original price.
100 +33.33%= 133.33
then divide by 100
= 1.33
this is the multiplier
$66 x 1.33= $87.78
$87.78 -$66 = $21.78
So the answer to the question is $21.78
Hope this helped Xx
