Answer:
$44.10
Step-by-step explanation:
The sale price of the shoes is (1.00-0.40)($70), or $42.
The final price, including tax, is (1.00 + 0.05)($42), or $44.10.
Wouldn’t it be 30 over all??
3x - 2y = 12
6x - 4y = 24....reduce by dividing by 2
3x - 2y = 12...same equation as the first...means same line...means infinite solutions
