Answer:
$1628
Step-by-step explanation:
A laptop computer was marked up 100% from an original cost of $740.
Marked up price = 100% of $740
= $740
Current price of the Laptop = Initial price of the Laptop + Marked up price
= $740 + $740
= $1480
Last Friday, Judy bought the laptop computer and paid an additional 10% in sales tax. What was her total cost?
Sales tax = 10% of the cost of laptop
= 10% × $1480
Sales tax = $148
Judy's total cost = Price of the Laptop + Sales tax
= $1480 + $148
= $1628
The answer is 8 3/4 is the answer
Answer:
-1 1/5
Step-by-step explanation:
<em>Change the whole number 4 to an improper fraction</em>
-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1
<em>Reciprocal the 4/1 will become 1/4 then go to multiplication</em>
-4 4/5 ÷ 4/1 = -4 4/5 × 1/4
<em>Change to improper fraction the -4 4/5</em>
-4 4/5 ÷ 4/1 = -24/5 × 1/4
<em>Then simply multiply the two numerators and the two denominators</em>
-4 4/5 ÷ 4/1 = -24/20
<em>Finally, Simplify it to get the answer</em>
-4 4/5 ÷ 4/1 = -1 1/5
Answer:
25%
Step-by-step explanation:
Say we start from the beginning with $40. If the pants are discounted but we don't know the percent discount, then we need a variable, x:
40 - x% * 40 = 30
The total is 40. When we take a discount off of 40, we are taking a percent of 40 and subtracting that from 40. From the problem, this should be 30. Thus, the equation above.
Add x%*40 to both sides and subtract 30 from both sides:
x%*40 = 10
Divide by 40:
x% = 1/4 = 0.25
Multiply each side by 100:
x = 25
The answer is 25%.
