Question

Josef receives a weekly allowance on the chores he does . He is given $10 up front and a additional $3 per hour for every hour that he works on chores . Which function rule can Josef use to find m , the amount of money he will have after a week of doing x hour of chores ?

a. m=10+3x
b. m=3+10x
c. m=13x
d. m=10x

Answer 1

What do you think?

His allowance has a "fixed" part, the $10, that doesn't depend on the hours he works.

Then there is an additional part that is ADDED to the 10, which DOES depend on the hours he works, x.

Answer 2

Which equation models that?

Answer 3

a.

Answer 4

One equation gives him $13 for each hour worked.

One gives him $10 for each hour worked.

One gives him $10 flat rate + $3 per hour worked

One gives him $3 flat rate + $10 per hour worked.
