Kellan's neighbor went out of town for 9 days. Each day her neighbor was gone, Kellan earned $7 for walking her neighbors dog and $2 for watering her neighbors plants.
Write a numerical expression with parentheses for the total amount of money Kellan earned.
9(7 + 2)
To write a numerical expression with parentheses for the total amount of money Kellan earned, we need to calculate the total earnings for each day and then add them up.
Since Kellan earned $7 for walking the neighbor's dog and $2 for watering the neighbor's plants each day, we can write the numerical expression as follows:
Total amount earned = (7 + 2) x 9
In this expression, the numbers within parentheses should be added first, and then the result should be multiplied by 9 to account for the 9 days.
