8b+12-b=8+7b+4
7b+12=12+7b
-7b
7b-7b+12=12
-12 -12
0= 12-12
0=0
1)1.10w+2.35(172-s)=294.20
When you solve
1.10x+2.35(172-x)=294.20 solve for x
X water=88
S=172-88=84
2)2t+4(40-f)=100
When you solve
2x+4(40-x)=100 solve for x
X=30 for t
40-30=10 for f
Hope it helps
First we should calculate the amount of the finance charge
Finance charge=179.32×(0.16÷12months)
=2.39
New balance= previous balance-payments/credit+finance change+New purchases
New balance=179.32−85+2.39+117.42
=214.13
Good luck!
