3x+2(x-1)=9x=4
We move all terms to the left:
3x+2(x-1)-(9x)=0
We add all the numbers together, and all the variables
-6x+2(x-1)=0
We multiply parentheses
-6x+2x-2=0
We add all the numbers together, and all the variables
-4x-2=0
We move all terms containing x to the left, all other terms to the right
-4x=2
x=2/-4
x=-1/2
Answer:
<h2>12.1% profit</h2>
Step-by-step explanation:
Given data
total eraser= 87
cost =$3 each
Total cost of eraser= 87*3= $261
she sold 63 at $3.5
1. sales made for the 63= $220.5
2 sale made for the remaining= 87-63=24
24*3=$72
Total sales made = 220.5+72=$292.5
her profit= sales-cost
profit= 292.5-261=$31.5
therefore the percent profit is
=31.5/261*100
=0.12*100
=12.1%
