To find the total amount that Palmer spent, you would first add up all his purchases. This can be represented by adding $90 + $110 + $100, which adds up to $300.
To find out how much Palmer has left, just subtract $300 from his initial $350 ($350 - $300 = $50.) This gives you a final answer of Palmer having $50 in his bank account.
First, you have to set up a system of equations. You can see all of my work and explanation on the picture attached! The answer is 40 adult tickets. I hope this helped you!! :))
