Audryn added a $12 tip to a $68.73 restaurant bill. What percent tip did she leave? Round to the nearest tenth of a percent.
Elena L [17]
What percent of $68.73 is $12? We can find out what we have to multiply to $68.73 to get $12. We can substitute this with "x". So then, our equation becomes 68.73x = 12. From there, you just do basic algebra. 

You should get <span>17.4596246% which can then be rounded down to 17% depending on which place you're rounding it by.</span>

Water flows through a pipe at a rate of 91 fluid ounces every 2.5 weeks. Express this rate of flow in cups per hour. Round your
Ulleksa [173]

Answer:

Step-by-step explanation:

First, we convert:

  • ounces to cups
  • weeks to hours

Result of conversion:

  • 91 fluid ounces = 11.375 cups  (1 cup = 8 ounces)
  • 2.5 weeks = 420 hours (1 week = 168 hours)

To get the rate, we must divide the number of cups by number of hours

  11.375 cups / 420 hours = 0.027 cups per hour = 0.03 cups per hour (approximated)

Hope that helps!
