Answer:

<em>The school paid for printing 130 T-shirts</em>

Step-by-step explanation:

<u>Function Models</u>

We are given the cost of printing n T-shirts as the equation:

C=250+5.5n

For example, if 10 T-shirts were printed, the school would pay:

C=250+5.5(10)=250+55=\$305

We know the school paid $965 and are required to find the number of T-shirts that were printed. If we use the equation with C=965, we can solve it for n:

965=250+5.5n

965-250=5.5n \Rightarrow 5.5n=715

Solving:

n=715/5.5=130

The school paid for printing 130 T-shirts

scZoUnD [109]

Answer:

1.Solve for y in 2x+y=-3

y=-3-2x

2. Substitute y= -3 - 2x into 4x-2y=10

8x+6=10

3 Solve for x in 8x+6=10

x=1/2

​

4. Substitute x=1/2 into y = - 3 - 2x

y= -4

5. So you get...,

x=1/2

y=−4

​
