Answer:
35/3
Step-by-step explanation:

Simplify to get
9x+14=3(4x-7)
35=3x
x=35/3 or 11.66
Multiply the original price by the percentage off:
80 x 0.30 = 24.00
they saved $24.00
= 7/5
= 7 ÷ 5
= 1.4
*The fraction will be decreased and transformed to an integer if it is a whole number response or a decimal.*
