Hi! I have a math question. This is a two part problem.
This is the first question which I already found the answer to:
"Blair is ordering 150 T-shirts to sell at the school carnival. Company A charges $3 for each shirt, plus 6% of the total order for shipping. Company B charges $3.10 per shirt, plus 4% of the total order for shipping. Company C charges $3.20 per shirt with no shipping fee. Question 1 Part A Drag a company name into each box to show the total costs from least to greatest. Least Cost Greatest Cost
A. Company B. Company C. Company" The answer was A, C,D.
The next part is the screenshot. Thank you!

Blair chosen to purchase shirt from company B. Given:

Each shirt costs 3.10$

Shipping cost is 4% (0.04) of total order.

=>Total cost without shipping: 150 x 3.10 = 465$

=> Total cost with 4% of shipping: 465 + 465 x 0.04 = 483.6$

=> Total cost Blair paid for one shirt: C = 483.6/150 = 3.22$

The markup is 75% of original cost:

=> Blair can multiply the total cost for one shirt by 0.75

Blair will sell shirt with price which is equal to the sum of total cost for one shirt and markup:

=> P = 3.22 + 3.22 x 0.75 = 5.64$

Hope this helps!

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
