Step-by-step explanation:
Answer: The cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
Step-by-step explanation:
Let x be the cost of one sandwich and y be the cost of one cup of coffee.
By considering the given situation, we have the following equations :-
![4x+3y=23.75.................(1)\\\\2x+5y=19.75................(2)](https://tex.z-dn.net/?f=4x%2B3y%3D23.75.................%281%29%5C%5C%5C%5C2x%2B5y%3D19.75................%282%29)
Multiply 2 on both sides of equation (2) , we get
![4x+10y=39.5................(3)](https://tex.z-dn.net/?f=4x%2B10y%3D39.5................%283%29)
Subtract equation (1) from equation (3), we get
![7y=15.75\\\\\Rightarrow\ y=\dfrac{15.75}{7}=2.25](https://tex.z-dn.net/?f=7y%3D15.75%5C%5C%5C%5C%5CRightarrow%5C%20y%3D%5Cdfrac%7B15.75%7D%7B7%7D%3D2.25)
Put value of y in (1), we get
![4x+3(2.25)=23.75\\\\\Rightarrow\ 4x+6.75=23.75\\\\\Rightarrow\ 4x =17\\\\\Rightarrow\ x=4.25](https://tex.z-dn.net/?f=4x%2B3%282.25%29%3D23.75%5C%5C%5C%5C%5CRightarrow%5C%204x%2B6.75%3D23.75%5C%5C%5C%5C%5CRightarrow%5C%204x%20%3D17%5C%5C%5C%5C%5CRightarrow%5C%20x%3D4.25)
Hence, the cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
