Answer:
6 cream puff and 4 ice creams
Explanation:
i = ice cream
p = cream puff
p+i= 10
1.50p + 1.20 i = 13.80
Multiply the first equation by -1.2
-1.20p -1.20 i = -12.00
Add this to the second equation
1.50p + 1.20 i = 13.80
-1.20p -1.20 i = -12.00
----------------------------------
.3p = 1.80
Divide each side by .3
p =6
Now find i
p+i = 10
6+i= 10
i= 10-6 =4
