Question

Help, I'm sort of confused. Find the percent error. Round to the nearest whole percent if necessary. Each week, Mr. Jones goes to the grocery store. Mr. Jones estimates that he will spend $120 when he goes to the grocery store this week. He actually spends $94

Answer 1

My answer would be 22% error.

94 - 120 divided by 120 = -0.021666667.
Now multiply that answer by 100.
-0.021666667 times 100 = -21.6666667%
So it would be 22% error.

Answer 2

94/120=0.7833333333333333......
he spented 78.3333333333333....% of what he estimated
