Answer

The new balance is approximately 1000. The exact new balance is 948.

Work Step by Step

Find the new balance by adding together the amounts withdrawn then subtracting the total from the beginning balance. Estimate the new balance using front end rounding by rounding each expense, totaling the rounded expenses, rounding the beginning balance, then subtracting the total withdrawals from the rounded beginning balance. Step 1: $528 \approx 500$ $195 \approx 200 $ $235 \approx 200$ Step 2: $500 + 200 + 200 = 900$ Step 3: $1906 \approx 1900$ Step 4: $1900 - 900 = 1000$ Determine the exact new balance by totaling the actual expenses then subtracting the total expenses from the beginning balance. Step 1: $528 + 195 + 235 = 958$ Step 2: $1906 - 958 = 948$
