Drew's weekly allowance is $8.00.His friend Jan's weekly allowance is $10.Drew spends $3 a week and Jan spends $4 a week. Write two expressions to show how much money each person has at the end of the week. Use parentheses



Answer :

Drew = -3w + 8
Jan = -4w + 10

Since we are talkimg about one week, plug in 1 for w

Drew = -3(1) + 8
= $5
Jan = -4(1) + 10
= $6
If they both have 1 week's allowance before they spend their money, then the math is like so:

Drew -
8w - 3w = y, where x is $/wk earned and y is $/wk spent and y is $ remaining
(8-3)w = y
5w = y
This is 1 week, so:
5(1) = y
5 = y

Jan:
10w - 4w = y, where x is $/wk earned and y is $/wk spent and y is $ remaining
(10-4)w = y
6w = y
This is 1 week, so:
6(1) = y
6 = y

In one week -

Otherwise they are in debt and should learn to hide out until they earn their allowance. Hopefully also learning to live within their means, because the repercussions are usually awful.
