Garden a is doubled to get garden b
Answer:
Step-by-step explanation:
Problem 1
<em>Set Up the Proportion</em>
3 cm / 8 km = x / 20 km Cross multiply
3*20 = 8x Combine the left
60 = 8x Divide by 8
60/8 = x
7 4/8 = x
7 1/2 km = x
7.5 km = x
Problem 2
3 cm / 8km = 12 cm / x Cross multiply
3x = 12 * 8 Combine the right
3x = 96 Divide by 3
3x/3 = 96/3
x = 32 km
48% error because it would be 24% if it was out of 100 but u have to double it becuase its out of 200
This sort of problem is most easily worked using a financial calcualtor or app. Attached is the result of using the financial app available on a TI-84 calculator for finding future value. The arguments to the function are ...
... N — number of payments: 3
... I — annual interest rate (%): 4.95
... PV — present value: the value of the loan, 125,600
... PMT — payment amount: -1500. The sign is negative because this is money we're paying out
... P/Y — payments per year: 12 (payment is monthly)
... C/Y — compounding per year: 12 (interest is compounded monthly)
After 3 payments, the balance is $122,642.13.
