Answer:

The required expression is 0.85p.

Step-by-step explanation:

Consider the provided information.

Let the original price is p.

Now it is given that we need to write an expression that the original price p of an item less a 15% discount.

15% of p can be written as:

\frac{15}{100}\times p

0.15\times p

0.15p

The original price p of an item less a 15% discount.

This can be written as:

p-0.15p = 0.85p

Hence, the required expression is 0.85p.

Answer:

the percent of increase is 24%

Step-by-step explanation:

The percent of increase in general could be calculate as:

\frac{Vf - Vi}{Vi} *100

where Vf is final value and Vi is initial value.

From the question we know that Vi is equal to 25 and Vf is equal to 31. Replacing this values on the equation we get:

\frac{31-25}{25} *100=24%

That's mean that at second attempt the percent of increase is 24%, taking into account that at the first attempt a student get 25 questions correct.

If i purchase a product for $79.99 and two accessories for 9.99 and 7.00 how much will i owe after taxes applies 8.75%
ehidna [41]

Answer:

The price will be $105.47

Step-by-step explanation:

Given that i purchase a product for $79.99 and two accessories for $9.99 and $7.00. we have to find how much will i owe after taxes applies 8.75%

Now, the cost price of the product and the two accessories will be

$79.99+$9.99+$7.00

= $96.98

Now, also the tax applies at the rate 8.75%

∴ Tax=8.75\%\thinspace of\thinspace96.98

               =8.48575=8.49(approx)

Hence, the price which i owe after taxes will be $96.98+$8.49=$105.47
