Membership is discounted $2 for first month
c=cost of one month
d=discount=$2
x=# of months
xc - 2= total cost
x for 1 month is 1, c is always 12, -2 is constant
1 x(12) - 2=10 for first month
8 months
8c -2=total cost for 8 months
8 x 12 - 2= 94 for 8 months
− 10/8
− 15/12
− 20/16
− 25/20
− 40/32
These are all equal, the list could go on but here are many
On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.
First, let's find out how much $92 less is:
48 - 92 = -44
We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th.
The correct answer is C. The 14th.
Hope this helps!! :)
