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

Priya and Han both factored the number 80. Priya says they should both get the same answer even if they started with different f

meriva

Answer:

Priya is right.

Step-by-step explanation:

The factors of 80 is 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

The factor pairs of 80 are

1 x 80, 2 x 40, 4 x 20, 5 x 16 and 8 x 10

If Priya picks 2 x 40, then it's prime factorisation will be, 2 x 2 x 2 x 2 x 5 = 2⁴ x 5.

If Han picks, 5 x 16 = 5 x 2 x 2 x 2 x 2 = 5 x 2⁴ = 2⁴ x 5. This is the same.

Therefore, Priya is correct, because the factors of 80 are always the same, therefore which ever you start with, you'd always get the same answer.
