Then solve the system of equations, SHOWING ALL YOUR WORK.

Answer 1

Answer:

Candies

l = 25b                                       r = b(25 + 3)

Example: b = 10 bags

                l = 25 x 10                                 r = 10(25 + 3)

                l = 250 candies                         r = 10 x 28 = 280 candies

Bags

r = l + 3

Examples:     r = 15 bags                    l = 15 bags

                      15 = l + 3                         r = 15 + 3

                      15 - 3 = l + 3 - 3              r = 18 bags

                      12 bags = l
