Answer:
9
Step-by-step explanation:
4(4)-7=16-7=9
4x- 7
Let x=4
4*4 - 7
16 -7
35 and 55
x+(2×-15)=90
3x-15=90
3x=105
x=35
other angle is 35×2-15=55
Take the pre-sale price.
Divide the original price by 100 and multiply it by 30.
Take this new number away from the original one.
The new number is your discounted value.
