Question

Jessica sold 210 magazine subscriptions during a fundraiser at her school. The subscriptions either cost $23 per year or $45 for two years. Her sales totaled $6,150. How many one-year and how many two-year subscriptions did Jessica sell?

Answer 1

let x = # at $23, and y = # at $45.

y = 210 - x

23x + 45y = 6150

Substitute 210-x for y in the second equation and solve for x. Insert that value into the first equation to solve for y. Check by putting both values into the second equation.
