Steve and Stephanie need to complete 4 hours of housework for their allowances to be equal.
What is equation?
"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
Let 'x' represents the Steve's weekly allowances and 'y' represents the Stephanie's weekly allowance.
Let h represent the number of hours.
Steve receives $15 plus $1.25 for every hour he completes housework.
So, we get an equation,
⇒ x = (1.25)h + 15
Stephanie receives $5 for every hour she completes housework.
So, we get an equation,
⇒ y = 5h
We need to find the number of hours of housework they need to complete for their allowances to be equal.
When their allowances are equal,
⇒ x = y
⇒ (1.25)h + 15 = 5h
⇒ 3.75 h = 15
⇒ h = 4 hours
Therefore, they need to complete 4 hours of housework for their allowances to be equal.
