Step-by-step explanation:

From the question, we are informed that Tabitha started working at a coffee shop making $8.75 per hour and that every 6 months, she gets a $0.40 cents raise.

a. The formula to represent her hourly wage after each raise would be:

= $8.75 + 0.40m

where m = period of 6 months

b. Find her hourly wage at 3yrs.

First we should note that 3 years = 3 × 12 = 36 months. Therefore, we would have 6 periods in 36 months since there's an increase every 6 months.

Therefore, using the formula

= $8.75 + 0.40m

where m = 6

= $8.75 + 0.40(6)

= $8.75 + $2.40

= $11.15
