Question 429283
Albert earns $78 for working 6 hours.
 Which equation could be used to find the number of dollars, d, that Albert earns in 9 hours? 
:
I don't like any of these equations; the 2nd one is not even an equation.
:
Change the 1st one to
{{{d/78}}} = {{{9/6}}}, that would work
6d = 9 * 78
6d = 702
d = 702/6
d = $117 earned in 9 hrs
:
:
Confirm this by finding the amt earned per hour, 78/6 = $13 per hr, 
Then in 9 hrs; 9 * 13 = $117
