Answer:
5 shirts
Step-by-step explanation:
Y=12x+3 equation 1
y=8x+23 equation 2
12x+3=8x+23 substituting y value will cause equations to equal
4x=20
x=5 shirts
check answer
y=12x+3
y=12(5)+3
y=60+3
y=63
y=8x+23
y=8(5)+23
y=40+23
y=63
Answer:
![3\ track\ practices](https://tex.z-dn.net/?f=3%5C%20track%5C%20practices)
Step-by-step explanation:
Let
d ----> distance Tess runs in miles
p ---> the number of track practices she attends
we have
![d=p+8](https://tex.z-dn.net/?f=d%3Dp%2B8)
This is a linear equation in slope intercept form
where
The slope or unit rate is
![m=1\ mile/track](https://tex.z-dn.net/?f=m%3D1%5C%20mile%2Ftrack)
The y-intercept (value of d when the value of p is equal to zero) is
![b=8\ miles](https://tex.z-dn.net/?f=b%3D8%5C%20miles)
so
For d=11 miles
substitute in the linear equation and solve for p
![11=p+8](https://tex.z-dn.net/?f=11%3Dp%2B8)
solve for p
![p=11-8\\p=3\ track\ practices](https://tex.z-dn.net/?f=p%3D11-8%5C%5Cp%3D3%5C%20track%5C%20practices)
You just put the number in for m with the formula you have. 12 months will give you T=2800.4*12 T will be 62) $33604.80 and with 36 months T=2800.4*36 will be 63) $<span>100814.40</span>
