Q. 3 tins of beans and 4 tins of tomatoes costs £2.73, and 5 tins of beans costs £1.55. Work out how much one tin of tomatoes costs.
Set up equations: Step 1: Set up equations based on the given information.Equation 1: 3B+4T=£2.73 (3 tins of beans and 4 tins of tomatoes cost £2.73)Equation 2: 5B=£1.55 (5 tins of beans cost £1.55)
Solve Equation 2: Step 2: Solve Equation 2 for B (price of one tin of beans).5B=£1.55B=£1.55/5B=£0.31
Substitute value in Equation 1: Step 3: Substitute the value of B in Equation 1.3(£0.31)+4T=£2.73£0.93+4T=£2.734T=£2.73−£0.934T=£1.80
Solve for T: Step 4: Solve for T (price of one tin of tomatoes).T=4£1.80T=£0.45
