Which situation is best represented by the following equation? 40w+12.50=492.50

The situation best represented by the equation 40w + 12.50 = 492.50 is:

A person earns $40 per hour and has already earned $12.50. The equation represents the total amount the person has earned, which is equal to $492.50. The variable "w" represents the number of hours the person has worked.

Which situation is best represented by the following equation? 40w+12.50=492.50

The situation best represented by the equation 40w + 12.50 = 492.50 is:

A person buys multiple items that each cost $40 and also spends an additional $12.50. The equation represents the total cost of the items and additional expenses, which is equal to $492.50. The variable "w" represents the number of items purchased.

Bella bought b boxes of cookies to bring to a party. She decides to keep two boxes. Each box contains 18 cookies. She brings 90 cookies to the party. Which equation can be used to find the number of boxes, b, Bella bought? How many boxes did she buy?

18b-2=90;b=5
2b-18=90;b=54
18b-36=90;b=7
18b-36=90;b=6

The correct equation that can be used to find the number of boxes, b, Bella bought is:

18b - 2 = 90;

Using this equation, we can solve for b:

18b = 90 + 2;
18b = 92;
b = 92/18;
b ≈ 5.11 (rounded to the nearest whole number)

So, Bella bought approximately 5 boxes of cookies.

Delia spent $250 to rent a boat for 6 hours. The rental company charges a base rate of $150 for the first two 2 hours, and then an hourly rate for each additional hour. How much does each additional hour of boat rental cost?(1 point)

To find how much each additional hour of boat rental costs, we need to subtract the base rate for the first two hours from the total cost and divide it by the additional hours.

Let's break down the given information:
Total cost of boat rental = $250
Base rate for the first two hours = $150
Additional hours = Total hours - Base hours = 6 - 2 = 4 hours

To find how much each additional hour costs:
Additional cost = (Total cost - Base rate) / Additional hours
Additional cost = ($250 - $150) / 4
Additional cost = $100 / 4
Additional cost = $25

So, each additional hour of boat rental costs $25.

Solve the equation for y. −1/5y+3=−7

To solve the equation −(1/5)y + 3 = −7 for y, we can follow these steps:

1. Start by subtracting 3 from both sides of the equation to isolate the term with y.
−(1/5)y + 3 - 3 = −7 - 3
−(1/5)y = -10

2. Next, to get rid of the coefficient −(1/5) in front of y, we can multiply both sides by the reciprocal of -(1/5), which is -5/1:
(-5/1) * (-(1/5)y) = (-5/1) * (-10)
y = 50

The solution to the equation is y = 50.
