I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
It's scientific notation, so 1.4x10^7 would be 14000000 <span />
<span>5,10,15,20,25,30,35,40,45,50,55,60 or 6,12,18,24,30,36,42,48,54,60,66,72</span>
9 servings, 5×3=15 but for each 5 equals 3 so,3 +3+3 =9 because 5 is a serving
Step-by-step explanation:
your answer is 60
hope it helps :)
