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)
Answer:
31
Step-by-step explanation:
We want to estimate 6207 / 214
Round 6207 to 6200
and 214 to 200
6200/200
62/2 = 31
We know that our estimate will be a little high since we are rounding the denominator down
The answer to that question is x = 2.5 I’m pretty though that question is a pretty weird one.
11,798.786 gallons (Don't know what place you want it rounded to, if at all) Assuming 3% evaporates per day, that is how many gallons will be left after 10 days.
