Lesson 2.10 HW Flashcard

Front

What is the total cost formula for a car wash fundraiser that charges $10 per car and $20 per truck, given a fixed cost of $90 for supplies?

Back

Total Cost = Fixed Cost + (Number of Cars * Price per Car) + (Number of Trucks * Price per Truck) = 90 + (10 * Number of Cars) + (20 * Number of Trucks)

Front

If a soccer team wants to raise $460 after spending $90 on supplies, what is the total revenue they need to generate?

Back

Total Revenue Needed = Goal Amount + Cost of Supplies = 460 + 90 = $550

Front

How do you calculate the number of cars needed to wash if a certain number of trucks have already been washed?

Back

Use the equation: Total Revenue Needed = (Number of Cars * Price per Car) + (Number of Trucks * Price per Truck) + Fixed Costs. Rearrange to solve for Number of Cars.

Front

What does the slope of a graph representing total cost versus number of items ordered indicate?

Back

The slope indicates the rate of change in total cost for each additional item ordered, showing how much the total cost increases with each additional item.

Front

In a fundraising scenario, how do you determine the number of items needed to meet a financial goal?

Back

Set up an equation based on the total revenue needed, including fixed costs and variable costs per item, and solve for the number of items.

Front

What is the significance of fixed costs in a fundraising event?

Back

Fixed costs are expenses that do not change with the number of items sold, and they must be covered by the total revenue generated.

Front

How can you represent a relationship between two variables, such as cost and quantity, using a graph?

Back

You can plot the total cost on the y-axis and the quantity of items on the x-axis, creating a linear relationship if the cost increases at a constant rate.

Front

What is the formula to find the total revenue generated from washing cars and trucks?

Back

Total Revenue = (Number of Cars * Price per Car) + (Number of Trucks * Price per Truck)

Front

If a team washes 15 trucks and needs to raise a specific amount, how do you find out how many cars they need to wash?

Back

Substitute the number of trucks into the total revenue equation and solve for the number of cars.

Front

What is the relationship between the number of days and the amount of food left in a bag, as shown in a graph?

Back

The graph typically shows a decreasing trend, indicating that the amount of food decreases over time.
