You spent these amounts on gasoline for the past four months: $67,$78,$53,$89. what should you budget for gasoline this month? a: $89 b: 70 c: 72 d$53

When we are making a budget based on the expenses we incurred in the previous months on the same commodity, we take the average of the expenses.

To find the average we add all expenses and divided by the number of expenses.

Here the expenses incurred in the previous months are $67, $78, $53 & $89.

The total expenses for the four moths are

= 67 + 78 + 53 + 89

= $287

To find the average we divided by 4

So average expenses = 287/4 = $71.75

So we must Budget $72 for this month.

Option C) is the right answer

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
