Final answer:
Elsie recycled 4 bottles and 17 cans.
Step-by-step explanation:
Let's represent the number of bottles as 'x'. Therefore, the number of cans can be represented as '4x+1', since it is one more than four times the number of bottles.
Given that Elsie earned 12¢ for each bottle and 10¢ for each can, we can set up the equation: 12x + 10(4x+1) = 218.
Solving this equation, we get:
12x + 40x + 10 = 218
52x + 10 = 218
52x = 208
x = 4
So, Elsie recycled 4 bottles and the number of cans is 4(4)+1 = 17.
