Marvin Co. sells pens ($6) and flashlights ($10). If total sales were $624 and customers bought 7 times as many pens as flashlight, what would be the number of pens sold?

the total sales is the total of the money brought in by each items sale. So use the equation 624= 7x($6) + x ($10) and solve for x
OpenStudy (anonymous):
where 7x stands for the number of pens and x is the number of flashlights sold

do you have the option of 84?
OpenStudy (anonymous):
nope
OpenStudy (anonymous):
there is a none of these options so that must be it thanks

because x solves for the number of flashlights = 12, and there are 7 times as many pens, so 84 pens.
