Question

Emma buys some cans of cola at 28p each,and twice as many cans of orange at 22p each. she also buys ten fewer cans of lemonade than orange at 25p each. she spends £ 14.58. How many cans of cola did she buy?

Answer 1

Let Coca cola cans be x
Orange can = 2x
Lemonade cans =2x-10
Cost of x cola cans=28p.x
Cost of 2x orange cans=22p.2x
Cost of 2x-10 lemonade cans = 25p.(2x-10)
Total money spent =£14*58
44p.x+28p.x+50p.x-250=£14*58
122p.x=£14.58+250p
£14.58=1458p
122p.x=1458p+250p
122p.x=1708p
x=1708p/122p
x=14
She bought 14 cola cans.
