3) Write a ratio for the following word phrase. Write the fraction in lowest terms.
42in. to 22yd
14) If $230 is invested for one year at 13.913.9% simple interest, how much interest is earned?
Solution
A.
ratio = 42 in/22 yd
22 yd = 792 inch
ratio = (42/792) in = (7/132) in
B.
Principle = $230
rate = 13.9%
time = 1 yr
Interest = Principle*rate*time
Interest = 230*13.9*1/100 = $31.97
Interest = $31.97
