Question

Can anyone explain this please?

Answer 1

Answer:

a) p(t) = 8.25t - 5

b) p(11) = 90.75 - 5 = $85.75

Step-by-step explanation:

During a clothing store's Bargain Days, the regular price for T-shirts is discounted to $8.25. This means the new price of a T-shirt is $8.25 if it is bought during the clothing store's bargain days. Also, there is additional coupon for $5.00 off, regardless of how many shirts are purchased. This means $5 off the total amount that you pay for the T-shirts.

a) the rule for the function, p(t) that expresses the final price of t T-shirts with the discount applied would be

p(t) = 8.25t - 5

Where p(t)= the final price of t T-shirts

t = number of T-shirts.

b) During the bargain days, amount paid for 11 T-shirts would be

p(11) = 8.25×11 - 5

p(11) = 90.75 - 5 = $85.75
