Answer:
Step-by-step explanation:
12a) P = 5x + 2y
12b) P = 5(3) + 2(5) = 25 m
12c) 32 = 5x + 2y
if x = 1, then y = 13.5 NOPE y not a whole number
if x = 2, then y = 11 could work
if x = 3, then y = 8.5 NOPE y not a whole number
if x = 4, then y = 5 could work
if x = 5, then y = 3.5 NOPE y not a whole number and is less than x
