**Answer:**

x = 11

y = 43

**Step-by-step explanation:**

x = small number

y = large number

Set up a system of equations:

y = 10 + 3x

x + y = 54

Solve system by substitution: x + 10 + 3x = 54

4x + 10 = 54

4x = 44

x = 11

x + y = 54

11 + y = 54

y = 54 - 11

y = 43

Answers:

1. The n-intercept is 12. That means after 12 visits the amount of money on the gift car is $0.

2. The A(n)-intercept is 150. Before the visits, the amount of money on the gift car is $150.

Solution:

Amount of money on the gift card after n number of visits: A(n)=$150-$12.50 n

A(n)=150-12.50 n

1. n-intercept

A(n)=0→150-12.50 n =0

Solving for n: Subtracting 150 both sides of the equation:

150-12.50 n-150 = 0-150

-12.50 n = -150

Dividing both sides of the equation by -12.50:

(-12.50 n) / (-12.50) = (-150) / (-12.50)

n=12

The n-intercept is n=12; for n=12→A(12)=0. Point (n, A(n))=(12,0)

2. A(n) intercept

n=0→A(0)=150-12.50 (0)

A(0)=150-0

A(0)=150

The A(n) intercept is 150; for n=0→A(0)=150. Point (n, A(n))=(0,150)
