1 answer:
vitfil [10]3 years ago

Answer:

B

Step-by-step explanation:

This is a simple interest problem. The formula for simple interest is:

i=Prt

Where

i is the interest amount

P is the principal amount

r is the rate of interest

t is the time in years

Given P, r, and t, we need to find convert r (as a percentage) to a decimal. We simply divide by 100. Shown below:

r = 7% = 7/100 = 0.07

Now, we substitute into formula and find i (interest):

i=Prt\\i=(300)(0.07)(2)\\i=42

Correct answer is B, $42

A linear function is a straight line, so that's clearly not it

A quadratic function has one point where is switches from going up to going down (or down to up), but this has two, so that's not it.

A cubic function has 2 points where it goes from down to up or up to down, so this may just work.

An exponential function has a constant to the power of something, so it's either staying constantly up or down after 0 or jumping up and down with every x value, which it isn't doing.

Logarithmic functions are similar to exponential functions in that it usually stays either going up or down the whole time.

Using our definitions, a cubic function is the only one that fits
