A $12 t- shirt is on sale for 40% off at a store in Mississippi. Sales Tax on Mississippi is 9%. How Much Will The t- shirt end

STALIN [3.7K]

Let's calculate how much for the $12 t - shirt after the discount.

First, convert 40% into a decimal,

$40\% = 0.4$

Next, multiply the cost by the discount,

$12 \times 0.4 = 4.8$

Lastly, subtract the amount discounted,

$12 - 4.8 = 7.2$

~~

Now

Let's calculate the amount after the sales tax,

First convert 9% to a decimal,

$9\% = 0.09$

Next, multiply the cost of the t - shirt by the sales tax,

$7.2 \times 0.09 = 0.648 = 0.7$

Lastly, add the amount of sales tax to the price of the t - shirt,

$7.2 + 0.7 =7.9$

~~

Answer : the t - shirt will be $7.90 after everything.

Answer: After 5 minutes, the plane is at 20,000 feet. It descended a total of 10,000 feet.

Step-by-step explanation:

f = feet above ground

r = rate of descent

m = minutes

f = 30000 - r · m

f = 30000 - 20000m

After five minutes:

f = 30000 - 2000(5)

f = 30000 - 10000

f = 20000

then

=> 75% of X = 180

Now lets find the value of X

X = $\frac{180}{75\%}$

X = $\frac{180}{\frac{75}{100}}$

X = $\frac{180}{0.75}$

X = 240
