Answer:

Step-by-step explanation:

2 l + 2w = 34 ⇔ l + w = 17 ⇒ l = 17 - w ..... <em>(1)</em>

l w = 66 ..... <em>(2)</em>

<em>(1)</em> ----> <em>(2)</em>

(17 - w) w = 66

w² - 17w + 66 = 0 ⇔ (w - 6)(w - 11) = 0

w = 6 cm

l = 11 cm

77julia77 [94]

Answer:

$94.05

Step-by-step explanation:

Original price of jeans=$95

Discount=10%

New price=(100% - 10%) of $95

=90% × 95

=90/100 × 95

=0.9 × 95

=$85.5

Sales tax of 10%

10% of the new price

=10/100 × 85.5

=0.1 × 85.5

=$8.55

Sales tax =$8.55

Total amount paid for the jeans= sales tax + new tax

=$8.55 + $85.5

=$94.05
