A quarter = 0.25......200 quarters = 200(0.25) = $ 50
a dime = 0.10...150 dimes = 150(0.10) = $ 15
a penny = 0.01....300 pennies = 300(0.01) = $ 3
for a total of : 50 + 15 + 3 = $ 68

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
