Marian went shopping and bought clothes for 56.17

Question

and books for 44.98
. She then had a meal at the mall for 21.15
. Which is the best estimate of the total cost of her shopping trip?

Answer 1

To estimate the total cost of Marian's shopping trip, we can round each expense to the nearest whole number:

• Clothes: 56.17 can be rounded to 56.
• Books: 44.98 can be rounded to 45.
• Meal: 21.15 can be rounded to 21.

Now, sum the rounded amounts:

\[ 56 + 45 + 21 = 122 \]

Therefore, the best estimate of the total cost of Marian's shopping trip is $122.
