Answer:

there are only three simple steps (:

Step-by-step explanation:

1. identify the two points on the line

2. select one to be (x1, y,1) (rise over run) and the other to be (x2, y2)

3. use slope equation to calculate your slope (m=rise/run= y2-y2/x2-x1)

in the equation of a straight line (equation written y=mx+b) the slope is m and b is the y intercept. (where the line crosses the y axis) this is the slope intercept form)

During the worst periods of hyperinflation in a certain country, the price of food increased at a rate of 30% per month. State w
Serhud [2]

Answer:

It was an exponential increase

In 3 months, the bill will be $285.61

Step-by-step explanation:

First, this scenario is exponential, because the price of food is increasing with a percentage, based on the price that it was the previous amount.

Next, to find what the bill will be in 3 months, an equation needs to be made representing the situation.

Use the standard exponential equation: y = ab^x, where a is the initial amount, b is the growth rate, and x is the amount of time.

Plug in the values we know:

y = 130(1.3)^3

Solve for y

y = 285.61

So, 3 months later, the bill will be $285.61
