Mae king earns a weekly salary of $305 plus a 7.5% commission on sales at a gift shop.How much would she make in a work week if she sold 4,300 worth of merchandise

Answers

Answer:

Step-by-step explanation:

Mae king earns a weekly salary of $305 plus a 7.5% commission on sales at a gift shop. This means that the total amount that she can earn in a week is not fixed. If in a week, she sold 4,300 worth of merchandise, her commission on this amount of sales will be 7.5 % of 4,300

Commission on sales = 7.5/100× 4300 = 0.075×4300= $332.25

Amount of money made for the week will be the sum of her weekly salary and the commission earned on sales. It becomes

305 + 332.25 = $627.5

Angela had 2 cups of flour. She used 1 1/4 cups when making muffins. Angela says she has 3/4 cup of flour left. Is Angela's answer reasonable?

Answers

Angela's answer is reasonable because if you had 2, and you subtracted 1 and 1/4, you would be left with 3/4 left. You can easily check your work by doing
3/4 + 1 1/4 = 2

You invest $230 to start a sandwich stand and decide to charge $4.25 per sandwich, Set up a Linear Model that determines your profit or loss based on the number of sandwiches

Answers

so if you price tax (for you ) for $.10 cents  each and you sell 60 sandwich's in one week at  least your profit would be $31 approximately since bread last longer and you still have ingredients make sure you always have some and use coupons and discounts to buy deli meats and bread + condiment or what ever you need  to take the money you earn and buy and after 8 weeks you earn $1,500 then after buying a lot of stock you have $1,300 upgrade to a 500$ buying period to get water drinks and other popular food. sandwich to 4.00 $ water is 2 for 1.50 and any other food over 3.00 yu get the profit of about $2600  getting a used food trruck to caryy on th buisness 

Using the fact that cos(52) = 0.6157, find the measure of angle B if sin(B) = 0.6157.

Answers

Answer:  B = 38

===============================================

Work Shown:

If cos(A) = sin(B), then A+B = 90, where A & B are both acute angles in degree form.

In this case, A = 52, so,

A+B = 90

B = 90-A

B = 90-52

B = 38

Telling us that

cos(A) = cos(52) = 0.6157

sin(B) = sin(38) = 0.6157

cos(52) = sin(38)
