<PRE><B>Question 1106404</B>
Mary went shopping and bought 3 times as many tins of beans as jars of jam.
 A tin of beans cost €0.69 and a jar of jam costs €1.50.
 The total bill was €7.14.
:
let x = the number of jars of jam
then
3x = number of tins of beans
; 
 1.Write a linear equation to represent this information
.69(3x) + 1.50x = 7.14
 2.Solve the linear equation
2.07 + 1.50x = 7.14
3.57x = 7.14
x = 7.14/3.57
x = 2 
3.How many jam jars did Mary buy?
    2 jars of jam
4. How many times of beans did Mary buy? 
3(2) = 6 jars of beans

Check
2(1.50) = 3.00
6(.69)  = 4.14
