The denominator is 40
10-3=7 (number of students in the band who do not ride the bus)
7/40=0.175
0.174*100=17.5% chance
Hope this helps!
Answer:
x=3
y=-2
Step-by-step explanation:
2x - 5y = 16
3x + 2y = 5
Solve for x in the first equation.
2x - 5y = 16
2x = 16 + 5y
x = (16 + 5y)/2
x = 8 + 5/2y
Put x as 8 + 5/2y in the second equation and solve for y.
3(8+5/2y) + 2y = 5
24+15/2y + 2y = 5
24 + 19/2y = 5
19/2y = 5-24
19/2y = -19
y = -2
Put y as -2 in the first equation and solve for x.
2x - 5(-2) = 16
2x +10 = 16
2x = 16-10
2x = 6
x = 3
Based on the commission that Xavier receives from Art Van Furniture, the total value of the furniture sold is $5,500.
<h3>How much furniture did Xavier sell?</h3>
The commission that Xavier earns on his first $1,000 should be removed to be:
= 930 - (12% x 1,000)
= $810
This value of $810 is 18% of the balance of Xavier's sales:
= 810 / 18%
= $4,500
Added to the first $1,000, Xavier's total sales are:
= 4,500 + 1,000
= $5,500
