Tiffany’s pay varies directly with the number of hours that she works. If she earned $77.28 for 4 h of work, how much will she earn for 15 hours of work
15 (77.28/4)
Can I please have steps please
Damon's answer is clear.
Divide 77.28 by 4.
Multiply the answer by 15.
Maybe setting up a ratio makes sense to you ...
x/15 = 77.28/4
x = 15(77.28/4)
which is Damon's calculation.
To find out how much Tiffany will earn for 15 hours of work, we need to determine the relationship between her pay and the number of hours she works. The problem states that Tiffany's pay varies directly with the number of hours she works, which means that her pay per hour remains constant.
To find the constant pay per hour, we can set up a proportion using the given information:
Pay / Hours = Constant
Using the values given in the problem, we can set up the proportion:
$77.28 / 4 hours = Constant
To find the constant value, we can cross-multiply and solve for the constant:
4 hours * Constant = $77.28
Constant = $77.28 / 4 hours
Now that we have determined the constant pay per hour, we can calculate Tiffany's earnings for 15 hours of work. We multiply the constant value by the number of hours worked:
Earnings = Constant * Hours
Earnings = ($77.28 / 4 hours) * 15 hours
Earnings = $77.28 * (15 / 4)
Earnings = $77.28 * 3.75
Earnings = $289.80
Therefore, Tiffany will earn $289.80 for 15 hours of work.
