Answer:
(4, 1 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 11 → (1)
x - 3y = 1 → (2)
Adding (1) and (2) term by term will eliminate the term in y
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and evaluate for y
Substituting into (1)
2(4) + 3y = 11
8 + 3y = 11 ( subtract 8 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
Solution is (4, 1 )

Answer:
$189.00
Step-by-step explanation:
Using the total cost of the shoes before tax, but after the sale price and coupon were applied, $74.50, first add back the $20 discount from the coupon:
74.50 + 20.00 = 94.50
Then, add the new amount by itself to find the original price since the sale applied a 50% discount:
94.50 + 94.50 = $189.00
Step-by-step explanation:
the total sale price for the magazines were
2×4.95 = $9.90
so,
100% = 9.9
1% = 100%/100 = 9.9/100 = 0.099
6.75% = 6.75×1% = 6.75×0.099 = 0.66825 ≈ $0.67
so, he paid in total
$9.90 + $0.67 = $10.57
