Answer:

Step-by-step explanation:
Let
x ----> the number of t-shirts
y ----> the cost of buying T-shirts from Paula’s Printing in dollars
take two points from the given data
we have
(2,43) and (4,86)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values in the formula
step 2
Find the equation of the line in point slope form

we have

substitute

step 3
Convert to slope intercept form

Isolate the variable y



This linear equation represent a proportional relationship (the line passes through the origin)
BC = 19.1-10.4 = 8.7
19) AB = BC = 8.7
20) CG = 30.6 -8.7 =21.9
21) AG = 8.7 +30.6 = 39.3
22) FG = DG (DG = 30.6-10.4-8.7) = 11.5
23) EH = 8.7 + 11.5 +8.7 = 28.9
24) EJ = 8.7 + 11.5 + 21.3 = 41.5
You can rewrite the number as repeated multiplication<span> and perform the </span><span>multiplication.</span>
