Answer:q^12
Step-by-step explanation:
Yvaries as x means
y=kx where k is constant
y=2.5
x=6
find k
2.5=k6
divide bot sides by 6
2.5/6=k (leave as that an simplfy later)
if x=4, what is y
y=(2.5/6)*4
y=10/6
y=5/3
y=1 and 2/3
40 x 0.08875 = 3.55
40 + 3.55 = 43.55
the sum is $43.55
X + 0.4[6-x] = 0.5*6 0.6x = 0.6 x = 1 gallon the answer is, "one gallon".
