Illustrative Math 8th Grade Unit 3 Review

Front

What is the formula to calculate total pay when given an hourly wage and a sign-on bonus?

Back

Total Pay = (Hourly Wage * Hours Worked) + Sign-on Bonus

Front

Write the equation for the total cost of renting a venue with an initial charge and a per hour rate.

Back

y = (Hourly Rate * x) + Initial Charge

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change or the cost per unit in a given context.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept represents the initial value or starting point when x = 0.

Front

Calculate the total cost for 15 hours of service at a rate of $125 per hour with an initial charge of $750.

Back

Total Cost = (125 * 15) + 750 = $2,625

Front

If a slope is 3.25, what does this indicate in a real-world scenario?

Back

It indicates that for each additional unit (e.g., ride), the cost increases by $3.25.

Front

How do you convert a word problem into a mathematical equation?

Back

Identify the quantities involved, determine the relationships, and express them using variables and constants.

Front

What is the significance of the initial charge in a cost equation?

Back

It represents the fixed cost incurred before any variable costs are added.

Front

How do you determine the total pay for a nurse working a 12-hour shift at $8 per hour with a $50 bonus?

Back

Total Pay = (8 * 12) + 50 = $146

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.
