Answer:
Uber: 2x + 10
Lyft: 3x + 8
Explanation:
Uber: $10 is basically the charge. $2 is charged for every mile you travel, so if you travel for 2 miles (any number) you multiply that by two then add $10 to it to get the final value.
Lyft: $8 is the initial value. And for every mile, you get charged $3 for it
