Answer:
They used 6 vans and 3 buses
Step-by-step explanation:
x + y= 9
13x + 40y= 198
x= 9 - y
13(9 - y) + 40y= 198
117 - 13y + 40y= 198
27y= 81
y= 3
9-3= 6
Answer:
$218
Step-by-step explanation:
$100 times 100% = $200
9% of 200 = 200X.09 = 18
200 + 18 = 218
You do 8* 7 = 56 + 7 = 63/8
You do 4*3 = 12 + 1 = 13/4
63/8 - 13/4 = 37/8
