6c + 3t = 4800
8c + t = 4600 .....multiply by -3
----------------
6c + 3t = 4800
-24c - 3t = - 13800
---------------add
-18c = - 9000
c = -9000/-18
c = 500...so each car is 500
8c + t = 4600
8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600...and each truck is 600
selling 2 cars and 3 trucks...
2(500) + 3(600) = 1000 + 1800 = 2800 <==
Answer:
12.5
Step-by-step explanation:
We want to find 1/8 of 100 so we would write it as 100÷8 to get 12.5
Now we know that 12.5 is equivalent to 1/8 but let's double check.
12.5×8 is 100
1/8 ×8 is 8/8
100=8/8
Answer:
<u>The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Initial deposit = $ 1,250
Interest rate = 4.25% annual simple = 0.0425
Time of investment = 4 years
2. What was the balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years?
Let's recall the simple interest formula, as follows:
A = P * (1 + rt), where:
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the values we know:
A = P * (1 + rt)
A = 1,250 * (1 + 4 * 0.0425)
A = 1,250 * 1.17
A = 1,462.50
<u>The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50</u>
