Answer:

A = 28

B = 22

Step-by-step explanation:

All money will be recorded in pennies

Let A = the 45 Bulb

Let B = the 65 bulb

A + B = 50                                  (1)

45A + 65B = 2690                    (2)

Multiply (1) by   45 and subtract that from (2)

45A + 65B = 2690

45A + 45B = 2250        Subtract

          20B =   440

              B = 22

A + B = 50

A + 22 = 50

A = 50 - 22

B = 28

Check

45*28 + 22* 65  =

1260 +  1430 = 2690
