Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

A. 14 + 2 × 5 = 14 + 10 = 24 ≠ 22

B. (14 + 2) × 5 = 16 × 5 = 80 ≠ 22

C. 24 - 6 ÷ 3 = 24 - 2 = 22

D. (24 - 6) ÷ 3 = 18 ÷ 3 = 6 ≠ 22

Answer:

C. 24 - 6÷ 3

Step-by-step explanation:

It couldn't be A because you get 24 as the answer.

It also can't be B because you get 80 as an answer.

D is a definite no because you get 6 as the answer.

The Rodriguez family went to dinner at Pasta Palace. Mr. Rodriguez ordered a meal for $6.25; Mrs. R ordered a meal for $7.50; th
Romashka-Z-Leto [24]
Given:
Mr. Rodriguez :                          6.25
Mrs. R                                        7.50
2 children @ 4.99 each       <u>      9.98</u>
Subtotal:                                 23.73
Sales tax 7.25%                        1.72        *23.73 x 7.25%
Total tip 15%                         <u>    3.56  </u>      *23.73 x 15%
Grand total                            $29.01


Tips should be applied to pre-tax amount not post-tax. However, some companies compute tip based on post-tax amount. This means that the tip you are paying is computed based on the total amount of the meal as well as the sales tax you paid for the meal.

A discount store takes 50% off of the retail price of a desk. For the store's holiday sale, it takes an additional 20% off of al
Serhud [2]

We are given the retail price of desk as $320. The store takes 50% off of the retail price of desk, then its price would become half of the original.

So its new price would be $160.

Now it says that it takes an additional 20% off of all furniture on store's holiday sale. So we need to cut off 20% from new price $160.

Holiday discount = 20% of $160 = 0.2 × 160 = 32.

Final selling price would be = $160 - $32 = $128.

So $128 is the final answer.

X/2.7 + 3.6=4.8 solve for x
weqwewe [10]

Answer:

3.24

Step-by-step explanation:

1) minus the whole number, 3.6 from both sides:  

   x/2.7 +3.6 = 4.8 -----> x/2.7 = 1.2

2) multiply both sides by 2.7 to get the x value on its own:  

   x/2.7 = 1.2 -------> x = 3.24

3) finally x is on its own with a value on the other side... x = 3.24
