Answer:
x= - 35 over 89
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

x+−23=18x−1837
7
x−23=18x−18
Step 2: Subtract 18x from both sides.

x−23=−18
Step 3: Add 23 to both sides.
−89

x−23+23=−18+23
−89

x=5
Step 4: Multiply both sides by 7/(-89).

Step-by-step explanation:
You mean like in a decimal? It'd be 12.5 or 12.50.... Same thing.
Estimated amount that Mr. Jones thought would be spending each week for grocery = $120
Amount actually spent by Mr.Jones in the grocery store = $94
Error in calculation of the amount of spending = (120 - 94) dollars
= $26
Percentage error in calculation = (26/120) * 100
= (13/6) * 10
= 130/6
= 21.666 percent
= 21.67 percent
So there is 21.67% error in the calculation of Mr. Jones. I hope you got the answer you were looking for.
