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 for the 15% gratuity.”How should Antoine respond to Tess’s method?
Answer
A
“Tess, the best way to find 15% of $46.00 is to multiply 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 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.”
