Answer:
The percent error is 40%.
Step-by-step explanation:
5 (actual time) - 3 (estimated time) = 2
2 divided by 5 (actual time) = 0.4
0.4 x 100 = 40%
Mistake was at Step 5
Going from Step 4 to Step 5 you're supposed to:
Division first: 2 + (10 / 2)
Then Addition: 2 + 5
Solution = 7
Step 5 did addition first then division when it is supposed to do division first, then addition
I hope it helped you :) :) :)
