Answer: $36.69
Step-by-step explanation:
Okay, so let's first write the equation:
2.59*10 + 3d = 135.97
Now, let's work on isolating d by first simplifying the equation:
25.9 + 3d = 135.97
25.9 + 3d - 25.9 = 135.97 - 25.9
3d = 110.07
3d/3 = 110.07/3
d = 36.69
Okay, now let's check:
2.59*10 + 3*36.69 = 135.97
25.9 + 110.07 = 135.97
135.97 = 135.97
Okay, so so it costs $36.69 per pair of shoe.
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
