D)-$60 since there are 12 months and 5 dollars for each month. 5 x 12 = 60
Answer:
y = 48
Step-by-step explanation:
given y is directly proportional to x then the equation connecting them is
y = kx ← k is the constant of proportionality
To find k use the condition y = 36 when x = 30
k =
=
= 
y =
x ← equation of proportionality
When x = 40 then
y =
× 40 = 48
