A store sells t-shirts for $15 each and hoodies for $30 each. Write a set of equations to find 'c', the total cost if someone buys 5 t-shirts and 2 hoodies.

Equation 1: 5 * 15 = cost of t-shirts. Equation 2: 2 * 30 = cost of hoodies. Equation 3: (5 * 15) + (2 * 30) = c

Solving Multi-step Equation Problems Lesson Plan for Grade 8th Grade

I can write and solve multi-step equations to represent real-world problems.

1
Ivy bought 3 graphic novels and 4 chapter books. If graphic novels cost $12 each, the equation to find the cost of graphic novels is 3 x 12 = $36.
2
Ivy bought 3 graphic novels and 4 chapter books. If chapter books cost $10 each, the equation to find the cost of chapter books is 4 x 10 = $40.
3
Ivy spent $36 on graphic novels and $40 on chapter books. The equation to find the total amount of money Ivy spent is 36 + 40 = m, where m = $76.
