For the past two weeks Matthew saved an additional $20 from his allowance. He saved $110 during this time period. Write an equation to determine how much money Matthew typically saves form his allowance.

m= (110 - 2(20)) / w

m= typical amount of money saved each week

w= amount of weeks in this time period

Step-by-step explanation:

you would take the $110 he had saved up and subtract the additional $20 from the past 2 weeks which would be $40 or 2 times 20, and then you would take that total amount, which is why it is in parentheses, and divide it by the number of weeks that Matthew had been saving for that time period where he saved $110.

For example:

If Matthew had been saving for 5 weeks what you would do is,

m= (110 - 2(20)) / w

m= (110 - 2(20)) / 5

m= (110 - 40) / 5

m= (70) / 5

m= 14

therefore if Matthew had been saving for 5 weeks typically he would have saved $14 every week

(keep in mind this is only if he had been saving for 5 weeks if he had been saving for any other number of weeks the answer would be different)

Hope this helps! Be sure to comment with any questions!
