teacher buys 30 compasses and 50 rulers for $95. another teacher bought 40 compasses and 40 rulers for $116. how much is each item

Answer 1

We will use a system of equations to solve this problem:

(30C + 50R = 95)4 75

(40C + 40R = 116)3

120C + 200R = 380

-120C + 120R = 348

-----------------------------

0 + 80R = 32

R = 0.4

30C + 50(0.4) = 95

30C + 20 = 95

30C = 75

C = 2.5

Therefore, Rulers cost $0.40 and Compasses cost $2.50.
