morpeh [17]

Answer:

$5 bill

Step-by-step explanation:

If Rhonda has $13 and she has a $5 bill and 3 $1 bills, then she has

5 + 3(1) + x = 13

5 + 3 + x = 13

8 + x = 13

x = 5.

The last bill must be a $5 bill to equal the remaining $5.

balu736 [363]

Answer:

10 quarters and 15 dimes

Step-by-step explanation:

25 = Quarters +  Dimes

Total worth = $4.00 =  0.25* Quarter +  0.1*Dimes

so...

25 = Q + D ,     D = 25 - Q

4 =  0.25*Q + 0.1 * (25 - Q)

4 = 0.25 * Q + 2.5 - 0.1*Q

1.5 = 0.15Q

Q = 10

D = 15
