Answer:
C - 21:28
Step-by-step explanation:
this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.
For C I did this:
Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.
Let's test it out for the numerator now. 21 ÷ 15 = 1.4.
So there's your answer.
232.50
1550 / 100 is 15.5 so 15.5 = 1%, 15.5 x 15 = 232.5 = 15%
To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:
