Can anyone explain this ?

18. during a clothing store's bargain days, the regular price for t-shirts is discounted to $8.25.
you have an additional coupon for $5.00 off, regardless of how many shirts are purchased

a. write a rule for the function p(t) that expresses the final price of t t-shirts with the
discount applied
b. how much would you pay during bargain days for 11 shirts?

A function that expresses the final price of T-shirts with the discount applied is P(t) = $8.25t - $5.

The total amount I would pay for 11 shirts is $85.75.

A discounted price of a good is the reduced price for a good or service. The discount price of one shirt is $8.25. The discounted price for t-shirt can be determined by multiplying the price of one shirt by t. The total cost is $8.25t. A coupon of $5 is given regardless of the amount of shirts bought. This can be represented with this equation: P(t) = $8.25t - $5.

The price of 11 shirts can be determined using this equation:

= $8.25t - $5.

= $8.25(11) - $5.

90.75 - $5

= $85.75

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

the least common denominator is 40
