Madison gets an allowance of $6 every week. For every chore she does, her parents give her an extra $2.50 for that week. Daniel receives an allowance of $3 a week and gains $3.25 for every chore he does the same week. How many chores would have to be done by both of the children to earn the same amount of money?
2.5x + 6 = 3.25x + 3
Isolate the variable by:
subtracting 3 from both sides
2.5x + 3 = 3.25x
subtracting 2.5x from both sides
3 = 0.75x
divide 0.75 from both sides
4 = x
In terms of my example problem, the answer would be 4 chores
