Answer:
p = $15d - (7,000 + 0.84d)
Step-by-step explanation:
In this question, we are asked to given an equation that will represent the profit Dion makes when he has made a total of d deliveries.
We proceed as follows:
To calculate the profit, we need to subtract the cost price from the selling price.
Let’s start with the cost price. This refers to the total amount of money that is used to prepare the goods for sales and also spent on that cause. He charges $0.42 for gasoline per trip. This means it is a total of $0.84 for each delivery. This is because two trips will make a delivery. Total number of money spent on gasoline on deliveries is thus 0.84 * d = 0.84d. Now, we add the cost of Motorcycle he rides to be $7,000. The total money spent is thus $7000 + $0.84d
His selling price is simply the number of deliveries he has made multiplied by the amount of money he charges per trip. This is same as 15 * d= $15d
Profit is thus ; p = $15d - (7,000 + 0.84d)
Answer:
x = ± 19
Step-by-step explanation:
x² = 361
x = ±√361
x = ± 19
If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.
Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.
This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%
Answer:
80in²
Step-by-step explanation:
Hey There!
So the first step of this problem is to find the width of the scale drawing
To do so we need to find the scale factor
To find the scale factor we divide the length of the room by the length of the scale factor
32/8=4
so the scale factor is 4
now to find the width
40/4=10
so the width of the scale drawing is 10 in
now we can find the area given the length and the width
10x8=80in²
so we can conclude that the area of the scale drawing is 80in²
100 drops =1fluid ounce
1 drop= 1/100 ounce
Hence
10 drops =10/100=1/10
