Answer:
$45.01 tax
5 shirts
Step-by-step explanation:
7% of 643 is
0.07 * 643 = $45.01
1232 - (45.01 + 643) = 543.99
That leaves enough to buy 5 shirts
y=2 when x=2
3(2)=6
6+6y=18
6y=18-6
6y = 12
6y/6 = 12/6
y=2
Because you are amazing
x = 13/3
12(x - 1) = 40
Distribute
12x -12 = 40
Add 12 to each side
12x-12+12 = 40+12
12x = 52
Divide each side by 12
12x/12 =52/12
x =13/3
