Afamily daycare center charges a one-time $80 enrollment fee and $90 per week (w).

write an equation for the total cost (t) based on the number of weeks (w) that a child is enrolled.

t= ?

You would multiply the weekly amount by the number of weeks (w) and add that to the one time fee:

t = 90w + 80

c.
