Mario spent a total of $87.33 last week, but did not keep a perfect record of where his money went. fortunately, mario does have all but one of his receipts. he enters all of the information he has into his expense spreadsheet as show below.
transactions
oil change $18.95
gas in car $20.50
lunch out $12.68
golfing
total spent $87.33

how much did mario spent on golfing?
a. $35.20
b. $45.20
c. $47.88
d. $143.96

Mario spent $35.20 on golfing.

Step-by-step explanation:

Mario spent last week  total = $87.33

As per records of all of his receipts that he has, the transactions are as below:

Oil change = $18.95

Gas in car = $20.50

Lunch out = $12.68

Golfing =

Total spent = $87.33

Now we add all the expenses that is shown above and subtract from total spent to know his golfing expense.

= 18.95 + 20.50 + 12.68 = $52.13

Total spent = 87.33 - 52.13 = $35.20

Therefore Mario spent $35.20 on golfing.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
