Answer:

candy bars = a

cupcakes = b

a=1.5$

b=2.25$

Step-by-step 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

12 - 7.5 = 4.5 = 3a

a=1.5$

b=2.25$

If the puppy weighs 3 pounds every month for five months, (5 x 3), that means he will gain 15 pounds in 5 months. Ad when you add that the original weight, (23 + 15), the puppy will weigh 38 pounds five months from now.
