Hey there, still working through that packet. Could someone help explain how I would solve this problem? The answer in the packet says it's 420mL.

Question

Thanks in advance!

Calculate the fluid intake in mL for the meal. Assume a glass holds 8 oz.

1/3 glass orange juice
1/2pt of milk
1 tuna fish sandwich
1 popsicle (3 oz)

Answer 1

just add up the amounts (in fl oz):

(1/3)(8) + (1/2)(16) + 3 = 41/3 fl oz.

Now just convert that to mL.
1 oz = 29.57 mL

Hmmm. I get 404 mL
