Sam buys three biscuits and one cake. How much does Sam spend altogether?
We know that biscuits cost 20 pence each and cakes cost 25 pence each. Sam buys three biscuits and one cake. Sam spent three lots of 20 pence. We know that three times two is six. So three times 20 is 60. Sam spent 60 pence on biscuits. He spent 25 pence on cakes. One lot of 25 is 25.
So to work out how much Sam spends altogether, we need to add together the amount he spent on biscuits and the amount he spent on cakes. We know he spent 60 pence on biscuits and he spent 25 pence more on a cake. So let’s add 25 to 60. 60 pence add 10 pence is 70 pence. 60 add 20 takes us to 80 pence. And five more pence makes 85 pence.
Sam spent 85 pence altogether.
