135 ----- 100%
120 ----- x

Answer:
$1799
Step-by-step explanation:
We simply work backwards and write out an equation.
Lets call the initial price P.
First we have 15% off the initial price P which means that we are only paying 85% of the initial price: .85*P.
Next we use a coupon for 20% off the reduced price which means we only pay 80% of the reduced price: .80 * (.85 * P)
We know that the price paid was $1223.32, set that equal to .80 * (.85 * P)
and we find that P is $1799
Courtney has 56. 3x+8 3(16)+8
Matthew has 16. X
X+3x+8=72
4x+8=72
Sub 8
4x= 64
Divide by 4
X=16
The answer is 73 ounces. the gift weights 64 ounces ( 4 pounds ) alone and 64+9=73. *1 pounds = 16 ounces
