Please answer this I need help! There are 90 people going on the field trip. The budget allows for $542.94 total for tickets to
Aleks04 [339]

Answer:

5.52 or less

Step-by-step explanation:

The total cost must be less than or  equal to the budget amount

Total cost limit  ≥ fee + cost per ticket * number of tickets

542.94 ≥  45.82 + cost per ticket * 90

Subtract 45.82 from each side

542.94 - 45.82≥  45.82 -45.82+ cost per ticket * 90

497.12 ≥ cost per ticket * 90

Divide each side by 90

497.12≥cost per ticket * 90

497.12/90≥  cost per ticket * 90/90

5.52 ≥  cost per ticket

The sales tax in your state is 5% if a car costs $24,600 what is the total cost including tax?
Svetach [21]
<h2>Greetings!</h2>

Answer:

$25830

Step-by-step explanation:

If 100% of the car price is 24,600 , then you can imagine that extra 5% being added to this

100 + 5 = 105

So you need to find what 105% of the cost was.

To do this you can use the percentage formula:

Amount x \frac{percentage}{100}

Now, you can simply plug the values into this

24,600 x \frac{105}{100}

24600 x 1.05 = 25830

<h3>So the total cost including tax would be $25830!</h3><h3 /><h2>Hope this helps!</h2>

Help Me!48 divided by 3/8?
expeople1 [14]
Work out 3/8 of 48.

First of all divide 48 by the denominator:

48 ÷ 8 = 6 (this gives 1/8 of 48)

Now multiply this answer by the numerator:

6 × 3 = 18 (this gives 3/8 of 48)
