Answer:
Total cost=$25
Step-by-step explanation:
We can derive two expressions as follows;
Total cost for the First shipping company=Medium box charges+total additional charges
where;
Medium box charges=$20
Total additional charges=Charges per pound×number of additional pounds (n)
Total additional charges=1×n=n
replacing;
Total cost for the First shipping company=20+n....equation 1
Total cost for the second shipping company=Medium box charges+total additional charges
where;
Medium box charges=$15
Total additional charges=Charges per pound×number of additional pounds (n)
Total additional charges=2×n=2 n
replacing;
Total cost for the First shipping company=15+2 n....equation 2
Equating equation 1 and equation 2
15+2 n=20+n
2 n-n=20-15
n=5
Replace the value for n in equation 2
Total cost for the First shipping company=15+2 n....equation 2
Total cost=15+(2×5)=$25
Answer:
y = 4/3x - 12
Step-by-step explanation:
<u>Use Point Slope Form: (y - y1) = m(x - x1)</u>
<u />
<u>Step 1: Find the slope</u>
m = ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
m = ![\frac{-4 - (-8)}{6 - 3}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%20-%20%28-8%29%7D%7B6%20-%203%7D)
m = ![\frac{-4 + 8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%20%2B%208%7D%7B3%7D)
m = ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
<u>Step 2: Plug into point slope form</u>
(y - (-4)) = 4/3(x - 6)
y + 4 = 4/3x - 24/3
y + 4 - 4 = 4/3x - 8 - 4
y = 4/3x - 12
Answer: y = 4/3x - 12
Answer:
72 cupcakes
Step-by-step explanation:
Morgan can make 4 cupcakes with one cup of flour. She has 18 cups of flour and suppose she can make x cupcakes, then
1 cup of flour - 4 cupcakes
18 cups of flour - x cupcakes
Write a proportion:
![\dfrac{1}{18}=\dfrac{4}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B18%7D%3D%5Cdfrac%7B4%7D%7Bx%7D)
Cross multiply:
![1\cdot x=18\cdot 4\\ \\x=72\ cupcakes](https://tex.z-dn.net/?f=1%5Ccdot%20x%3D18%5Ccdot%204%5C%5C%20%5C%5Cx%3D72%5C%20cupcakes)
