Question

Marian went shopping and bought clothes for $66.17 and books for $44.98. She then had a meal at the mall for $20.15. Which is the best estimate of the total cost of her shopping trip?

Answer 1

Answer: The total cost would be $ 131.

Explanation:

Since we have given that

Amount for bought clothes = $ 66.17

Amount for books = $ 44.98

Amount for meal = $ 20.15

First we add all the amount to get the total cost.

Total cost is given by

$ 66.17 + $ 44.98 + $ 20.15 = $ 131.30 So, the good estimate of $ 131.30 is

$ 130.

Hence, the total cost would be $ 131.

Answer 2

Either 130 or 131 would be acceptable.

Explanation:

When we estimate, we do not use exact values.

66.17 is close to 66

44.98 is close to 45

20.15 is close to 20

Add the estimates together: 66+ 45+ 20 = 131

We could also estimate 66.17 to 65 which would give us an estimate of 130
