Answer:
It should be 10.50 x (100-30)/100 = 7.35
If you simplify the equation by adding the like terms, you get 3n+6=42
Then you can subtract 6 from each side
3n=36
Divide each side by 3
n=12
<span>62.19 • 32.5=2,207.745</span>
3 1/2 in mixed fraction is 7/2
4 1/2 in mixed fraction is 9/2
So we can write 2 of those fraction like multiplication by each other and it’s gonna be 7/2 (2+9/2)
