sukhopar [10]

Answer:

her first mistake was on line 3.

line 1: 80 + [2(3 1/2 + 1 1/2)]

line 2: 80 + [2(5)]

line 3: 80 + 10

line 4: 90

Step-by-step explanation:

on line 3 she added 80 + 2, but she should have multiplied 2 by 5. the correct steps would be:

line 1: 80 + [2(3 1/2 + 1 1/2)]

line 2: 80 + [2(5)]

line 3: 80 + 10

line 4: 90
