Rob spent half of his weekly allowance on candy. to earn more money his parents let him weed the garden for $7. what is his weekly allowance if he ended with $12?

Let Robs weekly allowances be X
he spent half f it n candy so he spent X/2
he gardened for $7 extra and at the end he had $12
so to calculate his weekly allowances, we will develop the following equation
X/2 +7=12
X/2=12-7
X/2=5
X=5x2
X=10
Rob's weekly allowance is $10
