It's easy to see that to obtain the total of milliliters of rainwater that Suzan collected on Saturday and Sunday is the sum of the milliliters that Suzan collected each day.
The problem that we need to be careful about is the units. So we need to pass all the numbers to milliliters, we already have one in this unit then we just need to transform one:
[tex]3.5L\ast\frac{1000mL}{1L}=3500mL[/tex]Now we can use the sum as:
[tex]mL\text{ total=}3500mL+560mL=4060mL[/tex]Then the correct answer is B, 4060 mL.
