Answer:

you end up with 75 divided by 3.

Step-by-step explanation:

75 divided by 3 - 8 + 8

add 60 and 15

3 - 2(4) + 2^3

multiply -2 by 4

3 - 8 + 2^3

multiply 2 by itself 3 times

3 - 8 + 8 (which gives you 3 again)

and you get 75 divided by 3

A family went to a baseball game. The cost to park cars was $5 and the cost per ticket was $21. Write a linear function in the f

Sophie [7]

Answer:

The total cost $y$ in dollars of going to the baseball game for $x$ people of a family can be given as:

$y=21x+5$

Step-by-step explanation:

Given:

At a baseball game:

Cost of car parking = $5

Cost per ticket = $21

To write an equation in the form of $y=mx+b$ representing the total cost of going to the baseball game.

Solution:

The total number of people in the family is = $x$

Using unitary method to find the cost of tickets for $x$ persons.

If 1 ticket costs = $21

<em>Then, $x$ tickets will cost in dollars</em><em> = </em> $21x$

Fixed rate for car parking = $5

Thus, the total cost $y$ in dollars of going to the baseball game for $x$ people of a family can be given as:

$y=21x+5$
