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

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.
