PLEASE HELP I NEED ANSWER FAST


Antoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00.

Tess says, “It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get $4.60 + $4.60 = $9.20 for the 15% gratuity.”

How should Antoine respond to Tess’s method?

A) “Tess, the best way to find 15% of $46.00 is to multiply mc013-1.jpg by $46.00 to get $3.07, which is the 15% gratuity.”

B) “Tess, you found 20% of the number because you added 10% and 10%. You need to add 10% to mc013-2.jpg of 10%. Add $4.60 and $2.30 to get $6.90, which is the 15% gratuity.”

C) “Tess, the best way to find 15% of $46.00 is to multiply 0.015 and 46.00 to get $0.69, which is the 15% gratuity.”

D) “Tess, you should use a table with 5% segments to find the gratuity. Each 5% segment has a value of $9.20, so that is the 15% gratuity.”
