Answer:
7t/5^3 + 5t^2 + 4t^3
Step-by-step explanation:
Correct option is A. Money saved is ′ $6 ′ .
Given
Regular price of the refrigerator = $600
i) Buying the refrigerator at 20 percent off regular price
Final Discount in this case = 20% (Regular price of the refrigerator)
= 20 / 100 × 600
= $120
ii) Buying it on sale at 10 percent off regular price and an additional 10 percent off sale price
Discount for the sale = 10% (Regular price of the refrigerator)
= 10/100 × $600
= $60
Sale price of the refrigerator = Regular price of the refrigerator − Discount for sale
= $600 − $60
= $540
Final Discount in this case = 10% (Sale price of the refrigerator)
= 10/100 × $540
= $54
Money saved if we buy as (case−i) = (Final Discount in (case.i)) − (Final Discount in (case.ii))
= $60 − $54
= $6
Therefore, Money saved is ′ $6 ′ .

Answer:
35 percent
Step-by-step explanation:
To solve this problem we multiply the amount by the percent and add them up to get the total amount times the percent
amount * percent + amount * percent = total amount * percent
4 * .20 + 12 * .40 = (4+12) * x
.8 + 4.8 = 16 x
Combine like terms
5.6 = 16x
Divide by 16
5.6/16 = 16x/16
.35 =x
35 percent
Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
