During an episode of hyperinflation that occurred in brazil in 1999, the price of food increased at a rate of 30% per month. if your food bill was r$100 one month during this period, what was it 4 months later? (r$ is the symbol for the real, brazil's unit of currency.) and is this linear or exponential?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
