12 A person's weekly take home pay includes a base salary of $379 plus 9% commission on

their weekly sales.

a) Declare a variable for weekly take home pay. Declare a variable for weekly sales.

Write a function expressing the weekly take home pay, in terms of the weekly sales.

b) If the weekly take home pay for a given week was $752. 77, what were the weekly

sales for that week?

a) y = 379 + 0.09x

b) The weekly sale was $4153.

Step-by-step explanation:

Given that a person's weekly take-home pay includes a base salary of $379 plus 9% commission on  their weekly sales.

a) Now, if we represent $y as the weekly take-home pay and $x represents the weekly sales, then the equation models the situation will be

y = 379 + 0.09x .......... (1) (Answer)

b) Now, if y = $752.77 (given) then from the equation (1) we get,

752.77 = 379 + 0.09x

⇒ 0.09x = 373.77

⇒ x = $4153.

Therefore, the weekly sale was $4153. (Answer)

∠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.
