Answer: $9.81
Step-by-step explanation:
Here, Tiffany buys a basket of watermelons on sale for $9 before tax.
Therefore, Initial cost of a basket of watermelons = $9
And, he sales tax is 9%.
Therefore tax on a basket of watermelons,
9% of 9 = 
But, The total cost of a basket of watermelons = initial cost + tax
= 9+0.81=9.81
Therefore, Tiffany pays $9.81 for the basket of watermelons.
Answer:
Green Material: <u>129.6</u> in³
Brown Material: <u>194.4</u> in³
Step-by-step explanation:
The volume of the bin is 4×18×9 in³ or 648 in³
20% of 648 is 129.6 in³ (brown material)
30% of 648 is 194.4 in³ (green material)
Let van =v and bus=b
V+6B=324
9V+3B=264×2 this will become
18V+6B=528 minus equ 1 from equ 2
-17V=-204 divide both side by -17
V=-204/-17=12
if V is 12 put it in equ 1
12+6B=324,6B=324-12=312 divide both side by 6
B=312/6=52
therefore the van and bus will take 12 and 52 persons respectively
