Answer:

108  gadgets

Step-by-step explanation:

We can use a ratio to solve

24 gadgets           x gadget

------------------- = ---------------

2.5 hours           11.25 hours

Using cross products

24 * 11.25 = 2.5 *x

270 = 2.5x

Divide by 2.5

270/2.5 = 2.5x/2.5

108 = x

The sales tax on the model rocket shown is $1.92. What is the percent of sales tax? A drawing of a model rocket with a tag label
astraxan [27]

<u><em>Answer:</em></u>

The sales tax is 8%

<u><em>Explanation:</em></u>

<u>We are given that:</u>

The price of the rocket is $24 and the sales tax is $1.92

To get the percentage of the sales tax, all we have to do is divide the sales tax by the price of the rocket and then multiply the quotient by 100 (to convert the ratio to percentage)

<u>This is done as follows:</u>

% of sales tax = \frac{tax}{price}*100

% of sales tax = \frac{1.92}{24}*100 = 8%

Hope this helps :)
