Q. 3 tins of beans and 4 tins of tomatoes costs £2.73. 5 tins of beans costs £1.55. Work out how much one tin of tomatoes costs.
Equations Given: Let's denote the cost of one tin of beans as B and the cost of one tin of tomatoes as T. We are given two equations based on the information provided:1) 3B+4T=£2.73 (for 3 tins of beans and 4 tins of tomatoes)2) 5B=£1.55 (for 5 tins of beans)We need to find the value of T.
Cost of Beans: From the second equation, we can find the cost of one tin of beans by dividing the total cost by the number of tins:5B=£1.55B=£1.55/5B=£0.31Now we know that one tin of beans costs £0.31.
Cost of Tomatoes: We substitute the value of B into the first equation to find the cost of T:3B+4T=£2.733(£0.31)+4T=£2.73£0.93+4T=£2.73Now we need to solve for T.
Solving for T: Subtract £0.93 from both sides of the equation to isolate the term with T: £0.93+4T−£0.93=£2.73−£0.934T=£1.80Now we divide both sides by 4 to find the cost of one tin of tomatoes.
Final Answer: Divide £1.80 by 4 to find the cost of one tin of tomatoes:T=£1.80/4T=£0.45So, one tin of tomatoes costs £0.45.
