Jill worked 6 days and Peter worked 8 days.

Solución

Let Jill's number of days be x. Then Peter worked x + 2 days because he worked two days more than Jill. Peter's total earnings = 30(x + 2) dollars. Jill's total earnings = 40x dollars. Since they earned the same amount, we have: 30(x + 2) = 40x Expanding the left side: 30x + 60 = 40x Subtract 30x from both sides: 60 = 10x Divide by 10: x = 6 So, Jill worked 6 days and Peter worked 6 + 2 = 8 days.

Let's break it down! Since Peter earned \( \$30 \) per day and worked two more days than Jill, we can represent the number of days Jill worked as \( x \). Therefore, Peter worked \( x + 2 \) days. Now, we can set up the equations based on their earnings: - Peter’s total earnings: \( 30(x + 2) \) - Jill’s total earnings: \( 40x \) Since they earned the same amount of money, we can equate the two: \[ 30(x + 2) = 40x \] Expanding this gives us: \[ 30x + 60 = 40x \] Now, isolate \( x \): \[ 60 = 40x - 30x \] \[ 60 = 10x \] \[ x = 6 \] So, Jill worked \( 6 \) days, and Peter, who worked two more days, worked \( 8 \) days. Hence, the answer is Jill worked \( 6 \) days and Peter worked \( 8 \) days.
