Final answer:
Rachel will make 26 monthly payments of $40 to pay off the $1000 camera purchase, resulting in a total payment of $1040.
Step-by-step explanation:
To calculate how much Rachel will pay in total to pay off the purchase, we need to determine the number of monthly payments she will make. She makes monthly payments of $40, so we divide the total cost of the camera ($1000) by the monthly payment ($40) to get the number of payments. In this case, 1000 / 40 = 25. Since we need to round up to the nearest whole number, Rachel will make 26 monthly payments.
Next, we calculate the total amount paid by multiplying the number of payments (26) by the monthly payment ($40). So, 26 x 40 = $1040. This is the total amount Rachel will pay to pay off the purchase.
