A graph titled Swimmers at City Pool has Temperature (degrees Fahrenheit) on the x-axis, and swimmers on the y-axis. A trend line goes through points (75, 25) and (85, 40). Compare the number of swimmers at City Pool and the outside temperature to make an interpolation.

What is the best estimate for the number of swimmers when the outside temperature is 75ºF?
15 swimmers
20 swimmers
25 swimmers
30 swimmers

answer: 2530

hope this

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
