Problem of the Week - Algebra and Up - Oct. 18, 2020 to Oct. 24, 2020

Algebra and Up: 

Question: There are 125% as many students in sculpture class as there are in drawing class. If there are 15 more students in sculpture class than there re in drawing class, then how many students are in drawing class? 

Answer: 60 students

Solution: 

We can solve this problem with a system of equations in which x represents the number of students in sculpture class and y represents the number of students in drawing class.

x = 1.25y

x = y + 15

We can solve this by reasoning that since x = x, that means that 1.25y = y + 15. If we solve for y, we find that y = 60. There are 60 students in drawing class.
