Question 168782
Note: 7% = {{{7/100 = 0.07}}}



Let x=weekly sales



Since "Carol earns $250.00 plus 7% of her weekly sales", this translates to {{{y=0.07x+250}}} where "y" is the amount she earned in total



{{{y=0.07x+250}}} Start with the given equation



{{{1097.91=0.07x+250}}} Plug in {{{y=1097.91}}}



{{{1097.91-250=0.07x}}} Subtract 250 from both sides.



{{{847.91=0.07x}}} Subtract



{{{847.91/0.07=x}}} Divide both sides by 0.07 to isolate x



{{{12113=x}}} Divide



So the answer is {{{x=12113}}} which means that her weekly sales was $12,113
