Arrón had $60 and spent $36 on a new video game. Brynn had $77 and bought a chemistry set. Afterward, Arrón and Brynn had the same amount of money left over. Which equation can be used to find b, the cost of Brynn's chemistry set?

24 = 77 - c

Step-by-step explanation:

Since both started off with an initial amount of money and then made a purchase to end up with the same amount of money this can be represented as the following where x is the amount of money left over and c is the cost of the chemistry set.

60 - 36 = x

77 - c = x

Since both are equal to x we can simply make both equations equal to one another.

60 - 36 = 77 - c   ... simplify it by subtracting 60 - 36

24 = 77 - c

We can now solve this equation

24 = 77 - c  ... subtract 77 from both sides

-53 = -c  ... the negatives cancel out

53 = c
