Two sandwiches and a juice cost £3.40. Four sandwiches and three juices cost £7.20. Which simultaneous equations show this information?
Select the Correct Answer:
2s + j = 7.2 and 4s + 3j = 3.4
2s + 4s = 3.40 and j + 3j = 7.20
4s + 3j = 7.2 and 2s + j = 3.4
Correct Choice:
4s + 3j = 7.2 and 2s + j = 3.4
Use the situations given to create two simultaneous equations. Two sandwiches and a juice cost £3.40 can be written as 2s + j = 3.4. Four sandwiches and three juices cost £7.20 can be written as 4s + 3j = 7.2.
