The table shows the annual increase in cost in t years for certain grocery items. based on the formula a = c(1 + r)t, which equation could you use to determine the cost in t years for a loaf of bread?

a)a = 3.60t(1.05)eliminate

b)a = 3.60(0.95)t

c)a = 3.60(1.05)t

d)a = 3.60(0.05)t

Option C

Step-by-step explanation:

Given that there is an annual increase in cost

If rate of increase is r then we have

C(1+r) for I year and for II year C(1+r)^2 etc

Hence for t years

A =

Option A is wrong because exponent t should be for 1.05

Option B is wrong because here 1-r is done instead of 1+4

Option C is correct because r =0.05 and C=3.60 is correctly substituted

Option D is wrong because 1 is not added to r

SO finally only option C is right
