Keystone Algebra: Module 1 Practice

Front

What is the inequality that represents Shawn's spending on tickets and sodas if a ticket costs $20 and each soda costs $5, with a maximum spending of $50?

Back

5x + 20 ≤ 50

Front

What is the solution to the inequality 5x + 20 ≤ 50?

Back

x ≤ 6

Front

What is the equation that describes the height of a plant that grows 0.05 cm per day starting from a height of 2 cm?

Back

h = 0.05d + 2

Front

If Christine sells a total of 50 tickets, with student tickets at $1.50 and adult tickets at $4.00, what is the system of equations that represents her sales?

Back

Let s = number of student tickets, a = number of adult tickets: s + a = 50 and 1.5s + 4a = 112.50
