A T-shirt shop charges $15 for an adult shirt and $12 for a youth shirt. The total charge for a shirt order was $489. Which equa
tion can be used to represent x, the number of adult shirts sold and y, the number of youth shirts sold? 12x 15y = 489 27x 15y = 489 15x 12y = 489 15x 3y = 489.
In the problem it says that x is the number of adult shirts which 15 and y is the number for a youth shirt. So it would be 15x 12y. Hope this helped! :D
Well, since 1 tank takes 60 minutes (hour) and the other takes 40 minutes , add those to get 100 minutes . Divide 6000 by 100 to see how long it takes to fill the tank
