2 cups of coffee and 3 cops of tea cost £10.10 Three cups of coffee and 3 cups of tea cost £15.10 work out how much one cup of coffee is and one cup of tea is

Since we have the same cups of tea and one less coffee you just have to do 15.10 - 10.10 which is 5 euros, which means that one cup of coffee is 5 euros and one cup of tea is 3 cents. (Or whatever you use for uk)

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!
