Plotting the functions is highly recommended.
For A, the area under 
over the interval [1, 2] is the area of rectangle with height 3 and width 2 - 1 = 1, so the area is
For B, the area under 
plotted over the interval [0, 2] is the area of a triangle with height 1 and base length 2, so the area is
Answer:
a. $49
b. $74.28
c. No
Step-by-step explanation:
The computation is shown below:
a. The store price is
= Purchase price + markup
= $35 + $35 × 40%
= $35 + $14
= $49
b. The price paid is
Since there is a markup of 40% and when it is added to 100% of cost so the selling price is 140% of the cost or 1.40 of the cost
Now the price paid is
$104 = 1.40 × cost
So, the cost is
= $104 ÷ 1.40
= $74.28
c. Now the markup is
= $100 - $75
= $25
The markup percentage is
= $25 ÷ $75
= 33.33%
No the store does not markup the price by 40%
It would take greater than 31.25 hours for Tim's price to be better. So in terms of whole hours it would take at least 32 hours of work for Tim's price to be better.
Answer:
95
Step-by-step explanation:
(8)(10)+6−27+(5)(8)−4
=80+6−27+(5)(8)−4
=86−27+(5)(8)−4
=59+(5)(8)−4
=59+40−4
=99−4
=95
hope this helped :)
