Question

Kamal sells 240 ice creams for a total of £640

 of the ice creams he sells are large. 

The cost of each large ice cream he sells is £3.80

All the other ice creams he sells are small.

He sells each small ice cream for the same cost.

Work out the cost of each small ice cream.

Answer 1

You can set this up as a system of equations:

x = cost of small ice creams

s = small ice creams

l = large ice creams

s + l = 240

xs + 3.80l = 640

Here we run into the issue of having three variables for a system of two equations. It looks like more information should be provided in your second sentence. Was the number of large ice creams given?

With that information, you could calculate the value of s and solve for x, the cost of each small ice cream.
