Question

You have space in your garden for 50 small flowering bulbs. Bulb A cost $0.45 each and

bulb B cost $0.65 each. Your budget allows you to spend $26.90 on bulbs. How many of bulb A and how many of bulb B can you buy?
_______number of bulb A
_______number of bulb B

Answer 1

A = 28

B = 22

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
