Answer:

Step-by-step explanation:

3 coins pulled are 10 cents or more

5 coins are under 10 cents

so 3 out of 8 coins are 10 cents or more

the jar contains 200 coins

This is a ratio problem 3 is to 8 as x (an unknown value) is to 200

3/8 = x/200 solve for x

times both sides by 200

200(3/8) = x solve directly here using a calculator

600/8 = x or keep similifying until you can divide more

300/4 = x easily I kept dividing the numerator and the

150/2 = x denominator by 2 until i got 150/2 = 75

75 = x

Answer: $y=4x-9$

Step-by-step explanation:

$y=mx+b$

I know b is -9 because there's where the line crosses the y intersection.

$y=mx-9$

To find ''m'', we can use 2 different methods. I'm going to use one that follows a formula. First, locate two points in the graph.

$(0,-9);(3,3)$

$m=\frac{y_2-y_1}{x_2-x_1}\\ m=\frac{3-(-9)}{3-0}\\ m=\frac{3+9}{3}\\ m=\frac{12}{3}\\ m=4$

$y=4x-9$

Step-by-step explanation:

So the final equation will look like this: $4500(1+0.02)^9^-^1$

The answer comes out to $5272.46721451 but rounding that to the nearest dollar would be answer choice D: $5272.
