Answer:
profit(n) = n * .50
Profit(10) = 5.00
Step-by-step explanation:
Profit = amount of candy bars sold * profit per candy bar
profit(n) = n * .50
Let the number of candy bars sold be 10 ( n=10)
Profit(10) = 10 * .50
= 5.00
When you added you only added 9 .50 terms which is why you only got 4.50 for your answer.
Answer:
-31
Step-by-step explanation:
0 equal nothing so you will do -32-4+5 to get your answer
The correct answer should be 192.
3(8)^2=3x64
Answer:
11.25 yards
Step-by-step explanation:
The first thing we must do is see what the volume of the tank would be, which due to the measurements they give us would be:
v = height * width * length
We are asked to calculate the length, therefore:
length = v / (width * height)
volume equals 525, width 16 2/3 (16.67) and height 2 4/5 (2.8), replacing:
length = 525 / (16.67 * 2.8)
length = 11.25
Which means that the length is 11.25 yards
Let x be the number of adult tickets and y be the number of student tickets.
From the first sentence we can set up both equations:
1) x + y = 48
2) 7x + 3y = 220
Rearrange #1 to isolate x:
x = 48 - y
Sub that into #2 and solve for y to get your answer:
7(48 - y) + 3y = 220
336 - 7y + 3y = 220
-4y = -116
y = 29
29 student tickets were sold.
