Answer:

r(x) = 135x  + 59

The first choice

Step-by-step explanation:

We have the number of children represented by p(x) = 64x + 21

the number of adults represented by q(x) = 38 + 71x

for x = number of days that the pool was opened during July.

function r(x) is suppose to represent the total number of children AND adults.

so  r(x) =  p(x) + q(x)

r(x) = (64x +21)  +  (38 + 71x)

r(x) = 64x + 71x + 21 + 38

r(x) = 135x  + 59

Answer:

r(x)=135x+59

thats the answer :D
