cambridge has a job mowing lawns. he mowed 5 lawns last week and earned $82.50. the table shows his earnings for the week. which coordinate pair represents the unit rate for this situation?
a)
(0, 0)
b)
(1, 16.5)
c)
(3, 49.5)
d)
(5, 82.5)

B)  (1, 16.5)

Step-by-step explanation:

Given: Cambridge has a job mowing lawns.

He mowed 5 lawns last week and earned $82.50.

For this the unit rate=

Thus ,the unit rate for this situation=[tex]\frac{82.50}{5}[\tex]

hence, the unit rate for this situation = $ 16.50 per lawn

Therefore, the unit rate is represent by the coordinate pair (1,16.5).

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

answer:

f(5/2) = 10/3

i hope this you!
