Let's say you're renting a boat
Let h = number of hours you rent the boat
if it costs $46 per hour to rent a boat, then it will cost a total of 46*h or 46h dollars
Now let's say that you get a discount if you are a member. The membership fee is $86 leading to the discount hourly cost to be $25 per hour. If you rent for h hours, then you pay a total of 86+25h dollars
Writing 46h > 86+25h will represent cases when the nonmembership option is more expensive (and the membership option more cheaper). Solving for h will help determine when the membership option is cheaper.
Answer:
question one is 2,251.02
question 2 is 579.58
Step-by-step explanation:
We can create an equation.
What percent is x
'of' indicates multiplication
'is' indicates an equal sign
So we have:
x * 42 = 28
42x = 28
Divide 42 to both sides:
x = 2/3
Multiply by 100 to convert to a percentage.
x = 66 2/3 %
