Four packs of sandwiches and five drinks cots £10.60.If one drink costs 80p,how much is each sandwich?
let sandwich be x and drink y
if four packs of sandwiches and five drinks cots £10.60, we have
4x%2B5y=10.60.....eq.1
if one drink costs 80p=£0.80, we have
5y=5%2A0.80
5y=4.00
then
4x%2B4.00=10.60.....eq.1
4x=10.60-4.00
4x=6.60
x=6.60%2F4
x=1.65
=> the price of sandwich is £1.65
