Final answer:

Amber has 10 dimes and 50 pennies.

Step-by-step explanation:

Let's assume that Amber has x dimes and 5x pennies.

Since a dime is worth 10 cents and a penny is worth 1 cent, we can write the equation: 10x + 5(1x) = 150 (in cents).

Simplifying the equation, we have 10x + 5x = 150. Combining like terms, we get 15x = 150. Dividing both sides by 15 gives x = 10.

Therefore, Amber has 10 dimes and 50 pennies.

Answer:

50 pennies, 10 dimes

Step-by-step explanation:

0.01p+0.01d=1.50

p=5d

(0.01)5d+0.10d-1.50

0.05d+0.10d-1.50

0.15d=1.50

d=1.50/0.15

d=10

p=5d

=5x10

p=50

Answer= 50 pennies, 10 dimes
