Answer: 19

Step-by-step explanation:

The answer is 19 because, if n=5 then we have to divide 45 by 5. 45 divided by 5 equals 9. and to make sure we can multiply 9 and 5 and that equals 45. So now its saying what is 9 plus 10 and that equals 19. Just to make sure we can subtract 19 by 10 or 9 and if we do eitheer one they both equal 19.

Hope This Helps!

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline . If Mr. Adams spent $36.25 on 12.5 gal
Maslowich

Answer:

Step-by-step explanation:

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline .

Let the cost of regular gasoline be $x per gallon, then the cost of premium gasoline per gallon will be x + 0.14

If Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline, it means that 12.5x = 36.25

x = 36.25/12.5 = $2.9

The cost of regular gasoline is $2.9 per gallon

Therefore, cost of premium gasoline per gallon will be 2.9+ 0.14 = 3.04

if he bought 12.5 gallons of premium gasoline instead, he would have paid

12.5× 3.04 = $38

The amount that he would have spent more will be

38 - 36.25 = $1.75

Of the 725 students at Franklin Middle School, 12/25 play a sport. How many students play a sport at Franklin Middle School?
Paladinen [302]

Answer:

348 out of 725

Step-by-step explanation:

This is a ratio question, giving us a sample that we can use to extend the number to all students.

12/25 students play a sport so we want the value of x in x/725

So:

12/25 = x/725

Cross-Multiply:

25x = 8700

Divide by 25 to get x:

348

You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).

Katrina goes to Road Runner after school and purchases a soda for 1.50, chips for 3.50 and a candy bat for 0.50 An additional 8%
Nutka1998 [239]

<u>Answer:</u>

Sale tax paid by Katrina is 0.44 units of currency and total amount paid is 5.94 unit of currency.

<u> Solution:</u>

Given that Katrina goes to road runner after school and purchase following three products

A soda for 1.50  

Chips for 3.50

Candy for 0.50

Also she pays 8% sales tax.

Need to determine amount paid in sales tax and total amount paid by Katrina.

lets first calculate amount she paid without taxes.  

Total paid amount without taxes = 1.50 + 3.50 + 0.50 = 5.50

As she paid 8% sale tax , that is 8 % of 5.50

so sale tax paid = \frac{8}{100} \times 5.50 = 0.44

<em>Total amount paid = Total amount paid without taxes + tax paid </em>

= 5.50 + 0.44 = 5.94

Hence sale tax paid by Katrina is 0.44 units of currency and total amount paid is 5.94 unit of currency.
