Sale! 75% off
of the original price!
mia wants to buy a sleeping bag. the original price is $68. what is the sale price?
$

$17

Step-by-step explanation: To find the sale price, we first need to find the discount. To find the discount we use the formula shown.

Original price × rate of discount = sale price

In this problem, we are given that the sleeping bag is originally $68 and the rate of discount is 75% off or .75. Now, we multiply.

68 × .75 = 51

Now we know that the discount is $51.

Now, let's find the sale price. The formula for the sale price is shown below.

Original price - discount = sale price

The original price of the sleeping bag was $68 and the discount is $51. Now we have to subtract.

$68 - $51 = $17

Therefore, the sale price of the sleeping bag is $17.

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
