STORAGE COSTS According to a certain prediction equation, the cost of 200 square feet of storage space is $60. The cost of 325 square feet of storage space is $160. Find the slope of the prediction equation (in decimal form). Use the prediction equation to calculate the cost of 520 square feet. (use slash symbol to separate both answers, do not space)

for the first one it would be y=.8x-100 and the other answer would be 180

Let me know ASAP pls if it’s correct I found the answer online

Full answer is

.8 for 1st one

and 360 for 2nd one

Step-by-step explanation:

Correct answer was given after wrong one.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

560

hope this : )
