Choose all the expressions that are equal to 3.27÷ 100

a

Step-by-step explanation:

In solving this type of problem always look for the person you don't have any information about in this case  it's Eve therefore Eve is X, Justin has $7.50 more than Eve, therefore

X+$7.50 is Justin and Emma has $12 less than Justin, therefore subtract $12 from Justin X+$7.50-$12, since the total amount is $63 add all the numbers and equal them to $63.

x+7+x+7.5-12+ x=63

3x+3=63

3x=60

x=20

Plug in the x for each person

therefore Eve=$20

Justin=$20+$7.50= $27.50

Emma has $12 less than Justin therefore $15.50

Add all the money and it equals $63
