Answer:
9 basket balls, 15 foot balls
Step-by-step explanation:
Let x be the number of basket ball
y be the number of foot ball
1 basket ball = $22
so x basket ball = 22x
1 foot ball = $30
so y foot ball = 30y
Total cost = 648
The equation becomes 22x+ 30y = 648
Given : They bought 6 more footballs than basketballs.
foot ball (y) = 6 more basket balls(x)
so y = x + 6
we solve for x and y
Now we plug in x+6 for y in the equation 22x+ 30y = 648
22x+ 30(x+6) = 648
22x + 30x + 180 = 648
Subtract 180 on both sides
52x = 468
Divide both sides by 52
so x= 9
Number of basket ball x= 9
Number of foot ball y=x+6= 9+ 6 = 15
