Ainat [17]

Answer:

51 minutes.

Step-by-step explanation:

We have been given that for every 15 minutes of a show, there are two minutes to commercial. At this rate, Leila has seen 45 minutes of a show. We are asked to find the time for which Leila has been watching TV.

We will use proportions to solve our given problem.

$\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=\frac{15+2}{15}$

$\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=\frac{17}{15}$

Upon substituting our given values, we will get:

$\frac{\text{Minutes of TV show + Advertisement}}{45}=\frac{17}{15}$

$\frac{\text{Minutes of TV show + Advertisement}}{45}\times 45=\frac{17}{15}\times 45$

$\text{Minutes of TV show + Advertisement}=\frac{17}{1}\times 3$

$\text{Minutes of TV show + Advertisement}=51$

Therefore, Leila has been watching TV together for 51 minutes.

Mav went shopping for a new video game because of a sale. The store was offering a 15% discount. What number should she multiply

REY [17]

Answer:

.85

Step-by-step explanation:

Price she would have to pay =

(Price on Tag (Original Price)) - (Cost Discount) =

(Price on Tag) - (15%)(Price on Tag) =

(100%)(Price on Tag) - (15%)(Price on Tag) =

(100% - 15%)(Price on Tag) =

85% * (Price on Tag) =

.85 * (Price on Tag),

so .85 is the answer.
