1tin of 500ml blue paint costs $11.50. to finish a bedroom i need 4litre of blue paint. how much wi this cost me.

We know that 1 litre is equal to 1000ml (double the amount they're giving us), so 1 litre of paint is going to be $23 (we know this by multiplying 11.50 • 2).

Knowing this, all we need to do is multiply $23 • 4  which should give us $92.

So, the total of how much you will need to pay in this scenario to paint a room is $92 for 4 litres of blue paint.

Good luck! 

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
