PLZ HELP!!
Tim explained a function in words and Paul wrote an equation.

Tim

The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it.

Paul

y−1,400=56(x+26)

Whose function has the smaller y-intercept?

Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780

Answer:

Tim's with a y-intercept of $2,780

Step-by-step explanation:

To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.

Step 1. Get y by itself by adding 1,400 to both sides.

y-1400 + 1400 = y

56(x+26) + 1400 = 56(x+26) + 1400

New equation y = 56(x+26) + 1400

Step 2. Distribute 56(x+26)

56(x+26) = 56 * x + 56 * 26 = 56x + 1456

New equation y = 56x + 1456 + 1400

Step 3. Simplify.

y = 56x + 2856

Paul's y-intercept would be 2856 because when y=0 x=2856

To Find Tim's y-intercept, subtract 225 * 8 from 4580.

225 * 8 = 1800

4580 - 1800 = 2780

Answer:D or answer 4 or 2,780 dollars.
