Question

You have exactly $120to spend on a new outfit.if your state has 8% sales tax, what is the highest pre-tax price you can pay without going over
budget

Answer 1

The highest pre-tax price I can pay =x
I suggest this equation:
x+(8/100)x=120
least common multiple=100
100x+8x=12000
108x=12000
x=12000/108
x=111.11111...≈111.11$

The highest pre-tax price that i can pay without going over budget is $111.11
