Lyle wants to buy himself and his friends a sandwich and a pack of juice. A sandwich costs $0.30 while a pack of juice costs $0.2. If Lyle has $2.50, how many of his friends can have a sandwich and a pack of juice?
Let's be accurate as possible and think first.
4
A sandwich and a pack of juice cost $0.

3 + $0.

2 = $0.

50.

With Lyle's $2.

50, he can buy $2.

50 / $0.

50 = 5 sets of sandwiches and juice.

Therefore, 5 - 1 = 4 of his friends can have a sandwich and a pack of juice since the other 1 set is for Lyle himself.

.

So, the final answer is 4
