Answer:
8) 4
9) 16 OR 50.26548
10) 109.73452
Step-by-step explanation:
8) 8 ÷ 2 = 4
9) × 4² = 16 OR 50.26548
10) 8 × 20 = 160
160 - 50.26548 = 109.73452
In order to solve this question
Make an equation
Let x be the cost of each T- shirt
75x+6.25-20=398.75
Simplify the equation
75x-13.75= 398.75
Get Rid of The Constant
75x-13.75+13.75= 398.75+13.75
75x=412.5
Make sure your Variable is equal to one
75x÷75= 412.5÷75
x= 5.5
The price of each shirt is $5.50
I think it would be -2880
