Five candy bars and two cupcakes cost $12. Three candy bars and three cupcakes cost $11.25. Find the cost of each item

Answer 1

candy bars = a

cupcakes = b

a=1.5$

b=2.25$

Explanation:

candy bars = a

cupcakes = b

1)5a+2b = 12

2)3a + 3b = 11.25

We can understand

3a + 3b = 3(a+b)= 11.25

a+b = 11.25÷3 = 3.75

from No.2 equation.

than we do

(5a+2b) - 2(a+b)

and we got 3a

so

12 - 7.5 = 4.5 = 3a

a=1.5$

b=2.25$

Answer 2

$23.25

Explanation:

12+11.25
