The table compares x, the number of minutes of television Sam watched each day, to y, the number of minutes she spent exercising

Ahat [919]

For this case we have the following variables:

x: the number of minutes of television Sam watched each day

y: the number of minutes she spent exercising

Then, we have the following function that models the problem:

$y = -0.78x + 95$

if she spends 30 minutes watching television we have x = 30.

Substituting in the given equation we have:

$y = -0.78 (30) + 95\\y = 71.6$

Answer:

the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day is:

72 minutes

Ned has a coupon for one fourth off the cost of any item. Today all items are on sale for one third off. Does it matter whether

Aleksandr [31]

Answer:

Step-by-step explanation:

Let the cost of the item is C.

Case I :

first sale is applied

so, the price of item = one third = C - C/3 = 2C/3

Now coupon is applied

so, the price of item = $\frac{2C}{3}-\frac{1}{4}\times \frac{2C}{3}$ = C/2

case II :

First coupon is applied

so, the price of item = C - C/4 = 3C/4

Now sale is applied

the price of item = $\frac{3C}{4}-\frac{1}{3}\times \frac{3C}{4}$ = C/2

So, it does not matter that either coupon is applied first or the sale is applied first the final cost of the item remains same.
