Cody spent half of his allowance on candy. to earn more money his parents let. him wash the car for $7. what is his weekly if he ended with $17

Cody normally gets $10 per week 17=7=10 times 2=20

If x is the weekly allowance
1/2x+7=17
1/2x=10

x= $20

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
