Martin has a gift card to a coffee shop. Each day he buys the same coffee. The table shows the amount remaining on the gift card on different days.Which equation represents the situation?

Martin’s Gift Card
Days
2 4 5 7
Amount remaining 24.10 18.20 15.25 9.35


A.
y – 9.35 = −2.95(x – 7)

B.
y – 18.20 = 2.95(x + 4)

C.
y + 15.25 = −2.95(x + 5)

D.
y + 24.10 = 2.95(x – 2)

Answers

We want to see which linear equation represents the amount remaining on the gift card. We will see that the correct option is A:

y – 9.35 = −2.95(x – 7)

A linear equation in the point-slope form is written as:

y - y₁ = a*(x - x₁)

Where a is the slope of the line and (x₁, y₁) is a point on the line.

If we know two points on the line, (x₁, y₁)  and (x₂, y₂) then we can write the slope as:

a = (y_2 - y_1)/(x_2 - x_1)

Here we can use the two first points:

(2, 24.10)

(4, 18.20)

Then the slope is:

a = (18.20 - 24.10)/(4 - 2) = -2.95

Then the equation is something like:

y - y₁ = -2.95*(x - x₁)

Now, from the given options the only one where (x₁, y₁) is a point on the line is the first option, where:

x₁ = 7

y₁ = 9.35

So the correct option is A:

y – 9.35 = −2.95*(x – 7)

Gary invested $1,000 into an account earning interest at an annual rate of 5% compounded annually. Each year, he deposited an additional $1,000, and made no withdrawals. When he closed the account, he had a balance of $4,525.64. How much interest would Gary earn in that same time if he invests $10,000 and deposits $10,000 into the account each year?

Answers

so first we need to find out how much interest he earned a year so 525.64 divided by 4 which is 131.41 in interest a year so that 5% percent 

so 10000 $ for 4 year he would earn 1900.5 so he would have 11,900.5
