So first you have to move the -2 over to the opposite side. 8(9x-4)=3+2+2 Then you can simplify the right side 8(9x-4)=7 Then you distribute 8*9x=72x 8*-4=-32 so now you have... 72x-32=7 Then you move the 37 over 72x=39 Then you divide by 72 to isolate x x=39/72 or x= 13/24 or <span>x=0.54167</span>
To find what she saved you need to subtract 500-325= 175 then take 175 divided by the original price (500) to get a percentage so 175÷500=0.35 0.35= 35% so your answer is she saved 35%
