Solution:
<u>We know the following:</u>
- A student used a 30% coupon on a jacket
- The cost was $67.34 after the coupon was used.
<u>Thus, the equation created:</u>
- 67.34 + 30(Original price)/100 = Original price
Let's represent the original price as x. Then:
<u>Subtract 30x/100 both sides.</u>
- 67.34 + 30(x)/100 - 30(x)/100 = x - 30x/100
- => 67.34 = x - 30x/100
<u>Change x to 100x/100.</u>
- => 67.34 = 100x/100 - 30x/100
<u>Simplify the RHS:</u>
<u>Use cross multiplication.</u>
<u>Divide 70 both sides.</u>
- => x = 6734/70 = $96.2 (Original price)

Answer:
Step-by-step explanation:
2 * L + 2 * W = 68
2*L = 2* 9x = 9x + 9x
2*W = 2*8x = 8x + 8x
Since the perimeter is 68
9x + 9x + 8x + 8x = 68
