Answer:
Step-by-step explanation:
y = total cost and x = number of tons
y = 125x + 7500
the total cost for transporting 15 tons...sub in 15 for x
y = 125(15) + 7500
y = 1875 + 7500
y = $ 9375 <===== total cost
Answer:240
Step-by-step explanation:
40 pencils in one minute
2 hours=120 minutes
40*120=480
480/2=240 boxes
To solve A = P(1 + rt) for r, first isolate (1 +rt) by dividing both sides of this equation by P:
A/P = 1 + rt.
Next, isolate rt by subtracting 1 from both sides:
A/P - 1 = rt
Finally, divide both sides by t:
A/P - 1
----------- = r
t
This could be written in other formats, such as:
A - P
-------- = r
Pt
Solution:
Loan amount = $90,000
Given that this loan is 75% of purchase price of the new home.
We are required to to determine the amount paid for the home.
Let the amount paid for the home be x
The amount she paid for the home is $120,000 (Dollars)
1/8 + 1/6
= 1 x 3 + 1 x 4
——- ——
8 x 3 6 x 4
= 3/24 + 4/24
= 3 + 4
———-
24
= 7/24
