Hey there!!
Let's summarize the total cost for mountain bikes.
Materials - $60
Labor - $90
Let's take the number of mountain bikes as 'x'.
Total cost = 60x + 60x
... 120x
Let's summarize the total cost for trail bikes.
Labors - $60
Materials - $60
Let's take the total number of trail bikes as 'y'.
Total cost = 90y + 60y
... 150y.
____________________________________________________
Total cost for materials = $2,400
Hence,
60x + 60y = 2,400
____________________________________________________
Total cost for labor = $3,150
Hence,
90x + 60y = 3,150
____________________________________________________
Now, we have 2 equations.
... 60x+60y = 2400
... 90x+60y = 3150
Now let's subtract both these equations.
... 30x = 3150-2400
... 30x = 750
... x = 750 / 30
... x = 250.
<em>Hence, the number of mountain bikes the company plans to manufacture is </em><u><em>250. </em></u>
Hope my answer helps!
I believe its A ...................That question is such a drag -.-
Answer:
a. $1.50 per pound of weight.
b. C
Step-by-step explanation:
a. explanation:
1. pounds is increasing by +4 and dollars are increasing by +6.00
2. as a fraction it is 6/4.
3. simplified is 1 1/2 or 1.50
b. explanation
1. we know that the slope (or rate of change) is $1.50 /per pound of weight.
2. 4 - 4 = 0; $11.00 - 6.00 = $5.00
3. 0, $5.00
4. The y-int. is $5.00
5. answer is C
The miles previously covered by algae is 6 miles
let m represent the miles of the coastline covered by algae before the clean-up
fraction of miles covered after the clean-up =
x m = ![\frac{1}{3}m](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dm)
miles covered after the clean-up = 2 miles
= 2 miles
to determine the value of m, make m the subject of the formula.
To do this, take the following step :
multiply both sides of the equation by 2
m = 2 miles x 3
m = 6 miles
