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.
