Answer:
1 one-dollar bill
3 quarters
3 pennies
Step-by-step explanation:
5.00 - 3.22 = 1.78
1 one-dollar bill
3 quarters (25 x 3 = 75 cents)
3 pennies (3 x 1 = 3 cents)
So we have lengths a and b and are given:
2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272
plug in one into the other:
(33-b)b = 272 => -b^2 +33b - 272 = 0
Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.
So a=16 and b=17 or vice versa.
