Answer: 70
Step-by-step explanation:
Solve the equation in the innermost parentheses first that means solving 4+1 =5
The next step would be subtracting 9 from five which gives you 4
Next multiply 3 to 4 which gives you 12
Then multiply 5 with 12 which equals 60
Now you have the equation 60+20/4*2
Solve the division and multiplication part of the equation first because of the rule pemdas which shows multiplication comes before addition
First divide 20/4 which gives you 5 then multiply with 2 which gives you ten
After dividing and multiplying you are left with the equation 60+10
The answer is 70
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
