x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
The discount is $.40 (1.20 - 0.80)
To find the discount you take (0.40/1.20) * 100
=.33 * 100
The discount is 33%
1.)100+80+7+0.5+0.04 or you could do it like 2.)1x100+8x10+7x1+5x0.1+4x0.01
