Step-by-step explanation:

Betsy sells laptops at an electronics store. She earns $180 a week, plus $15 for every laptop she sells. Betsy needs to earn at least $900 this week to meet her sales goal. Write and solve an inequality that can be used to determine the number of laptops Betsy needs to sell this week.

Answers

Answer:

15x + 180 ≥ 900

x ≥ 48

Step-by-step explanation:

x = amount of laptops needed to sell.

Equation:

15x + 180 ≥ 900

15x ≥ 720

x ≥ 48

Check:

15(48) + 180 = 900

720 + 180 = 900

900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).

which polynomials are in standard form?

choose all answers that apply:

a. 3z-1
b. 2+4x-5x^2
c. -5p^5+2p^2-3p+1
d. none of the above

Answers

Answer:

A and C are the correct answers.

Step-by-step explanation:

Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.

In choice A, since 3z has a variable, it goes before 1. In choice C, since -5p^5 has the highest exponent it does go first. Then 2p^2, since it has the second highest exponent. Then -3p follows, with the lower exponent. Then 1 goes last because it has no variable and has the lowest exponent.

At a sale, books are sold at $90.75 each, which is 75% of the original price.

(i) what is the original price of the book?

(II) Paul buys 10 books at the sale and pays VAT of 16% on the sale price. Calculate the TOTAL amount he paid for 10 books.

Answers

Answer:

Selling Price= $90.75

(i) Original Price= $90.75/0.75= $ 121.00

(ii) 1 Book= $90.75

10 Books= $90.75*10= $907.50

Total Amount Paid= $907.50*1.16 =$1052.70

oday, everything at a store is on sale. The store offers a 20% discount. **NUMBERS ONLY. NO SYMBOLS.** a. The regular price of a T-shirt is $18. What is the discount price? b. The discount price of a hat is $18. What is the regular price

Answers

Answer:

Discount price of T-shirt is $14.40

Regular price of hat is $22.50

Step-by-step explanation:

The regular price, without a discount, of the T-shirt is $18. Since the store offers a discount of 20%, we must remove 20% of the price.

100%-20%=80%. So, the discount price is 80% of the regular price.

18 × 80% = 14.4

So, the discount price of the T-shirt is $14.40.

The hat, on a discount of 20%, costs $18. To find the regular price, we must multiply it by the reciprocal of 80%, which is 100/80, or 1.25.

1.25 × 18 = 22.5

So, the regular price of the hat is $22.50.
