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?

Either 130 or 131 would be acceptable.

Step-by-step 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

(23*2)-12=x     x=34

step-by-step explanation:

ok then what happened.
