Answer :
Final answer:
By solving a system of linear equations, it's found that tomatoes cost $0.50 per pound and bananas cost $0.30 per pound.
Explanation:
The question deals with a system of linear equations to find the price per pound of tomatoes and bananas.
Let t be the price per pound of tomatoes and b be the price per pound of bananas. From the given information, we construct two equations:
- 40t + 20b = 26
- 10t + 50b = 20
Solving this system step by step:
- Multiply the first equation by 1/4 to simplify: 10t + 5b = 6.5
- Subtract the modified first equation from the second equation to eliminate t: 45b = 13.5
- Now, solve for b: b = 13.5 / 45 = $0.30 per pound
- Substitute b = $0.30 back into one of the original equations to solve for t. Using 10t + 5(0.30) = 6.5: t = $0.50 per pound
Hence, tomatoes cost $0.50 per pound and bananas cost $0.30 per pound.
