Answer:
Packages A and C
Step-by-step explanation:
To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.
Package A = 3 : 30
Package B = 5 : 60
Package C = 12 : 120
Package D = 16 : 120
Now let's break it down.
Package A = 30/3 = $10 per lift
Package B = 60/5 = $12 per lift
Package C = 120/12 = $10 per lift
Package D = 120/16 = 7.5 per lift
So now we are able to know which packages have the same ratio.
Package A and C cost $10 per lift.
<span><span>K = k + 13</span><span>78</span></span>
Cross multiply:
K * 8 = 7 * k + 13
Simplifying
K * 8 = 7 * k + 13
Reorder the terms for easier multiplication:
8K = 7 * k + 13
Reorder the terms:
8K = 7 * 13 + k
8K = 13 * 7 + k * 7
8K = 91 + 7k
Solving
8K = 91 + 7k
Solving for variable 'K'.
Move all terms containing K to the left, all other terms to the right.
Divide each side by '8'.
K = 11.375 + 0.875k
Simplifying
K = 11.375 + 0.875k
there it was hard but i got it
