The number is 7</h3>
Step-by-step explanation:
x - a certain number
6x - - six times the number
6x-31 - six times the number less 31
3x - three times the number
3x-10 - 10 subtracted from three times the number
so the equation:
6x - 31 = 3x - 10
+31 +31
6x = 3x + 21
-3x - 3x
3x = 21
÷3 ÷3
x = 7
Check: 6•7-31=42-31=<u>11</u>; 3•7-10=21-10=<u>11</u>
D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.
