Will give brainliest pls its ! during a clothing stores bargain days, the regular price for t-shirts is discounted by $5. there is a state sales tax of 5%, and the $5 discount is applied before the sales tax is calculated, a. write an expression that shows the regular price r for a t-shirt minus the $5 discount. b. write a rule for the function p(r) that expresses the final price p of a t-shirt with the withe the discount applied and sales tax added. c. how much would you pay during bargain days for a shirt regularly priced at $15.50?

Answers:

a. Write an expression that shows the regular price r for a t-shirt minus the $5 discount

Expression=r-$5

b. Write a rule for the function p(r) that expresses the final price p of a t-shirt with the with the discount applied and sales tax added.

p(r)=1.05(r-$5)

c. How much would you pay during Bargain Days for a shirt regularly priced at $15.50?

You would pay $11.03 during Bargain Days for a shirt regularly priced at $15.50.

Solution:

a. Write an expression that shows the regular price r for a t-shirt minus the $5 discount.

Regular price: r

Discount: $5

Expression=r-$5

b. Write a rule for the function p(r) that expresses the final price p of a t-shirt with the with the discount applied and sales tax added.

Final price: p(r)

There is a state sales tax of 5%, and The $5 discount is applied before the sales tax is calculated:

p(r)=Expression+Sales tax

State sales tax=5%=5/100→State sales tax=0.05

Sales tax=State sales tax * Expression

Sales tax=0.05*Expression

p(r)=Expression+0.05*Expression

p(r)=(1+0.05)*Expression

p(r)=1.05*Expression

Expression=r-$5

p(r)=1.05(r-$5)

c. How much would you pay during Bargain Days for a shirt regularly priced at $15.50?

r=$15.50→p(r)=p($15.50)

p($15.50)=1.05($15.50-$5)

p($15.50)=1.05($10.50)

p($15.50)=$11.025

p($15.50)=$11.03

You would pay $11.03 during Bargain Days for a shirt regularly priced at $15.50.

15 units use socratic

step-by-step explanation: 15 units

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
