For each container of tea, McKenzie uses 16 tea bags and 3 cups of sugar. If McKenzie uses 64 tea bags, how many cups of sugar will she use?

A: 3/4 cup

B: 4 cups

C: 8 cups

D: 12 cups

So tis is a ratio 16 is to 3 or 16:3

if use 64 tea bags then how many cups of sugar so

turn 16:3 into fraction

16:3=16/3 or 3/16, it doesn't matter

then you want to find 64:x or 64/x or x/64

we know that 16/3=64/x because it tis an equivalent ratio

so 16/3=64/x

multiply both sdies by (3 times x)

16 times x times 3/3=64 times 3 times x/x

16 times x=64 times 3

16x=192

divide both sdies by 16

x=12

theanswer is 12 cups of sugar
