For this case, the first thing we must do is define a variable:
g: number of gallons of gas.
c (g): total cost.
We then have a linear function of the form:
c (g) = 2.19 * g
Answer:
A function notation to describe the relationship between the total cost c (g) and the number of gallons purchased is:
c (g) = 2.19 * g
Answer: 232x
Step-by-step explanation: (8x)(33+2)
=(8x)(33)+(8x)(2)
=216x+16x
=232x
it lost 128 gallons in 16 days so divide 128 by 16 to find the daily lost
128/16 = 8 gallons a day were lost
X/2 - 6 = 15
x/2 -6 +6 = 15 + 6
x/2 = 21
x/2 × 2 = 21 × 2
x = 42
Check
42 ÷ 2 - 6 = 15
42 ÷ 2 = 21 -6 = 15
