phone he sells and a $4 commission for every accessory he sells. On a given day, Jose made a total of $253 in commission and sold 8 more accessories than phones. Write a system of equations that could be used to determine the number of phones sold and the number of accessories sold. Define the variables that you use to write the system.

Answer:

Let p be the number of phones sold and a be the number of accessory sold.

9p + 4a = 253

a - p = 8

Step-by-step explanation:

He gets $9 for every phone and $4 for every accessory, so you can write this as

9p + 4a

Then he made a total of $253 do the new equation is

9p + 4a = 253

We are also given that he sold 8 more accessories than phones. So we can write this as

a = p + 8

rearrange that so that all the variables are to one side.

a - p = 8

Now you have the two equations needed to solve the for the variable. The question didn't ask me to solve for the variable so I'll leave it here.

Answer:

Step-by-step explanation:

Let x represent the number of phones sold.

Let y represent the number of accessories sold.

Jose earns a $9 commission for every phone he sells. This means that the total commission earned for selling x phones would be

$9x

He also earns a $4 commission for every accessory he sells. This means that the total commission earned for selling y accessories would be

$4y

On a given day, Jose made a total of $253 in commission and sold 8 more accessories than phones. The equation would be

9x + 4y = 253 - - - - - - - - -1

Since he sold 8 more accessories than phones, it means that

x = y - 8 - - - - - - - - - - - -2

Therefore, equations 1 and 2 can be used to determine the number of phones sold and the number of accessories sold.

In a study of pain relievers, 50 people were given product A, and all but 11 experienced relief. In the same study, 100 people w

Nataly_w [17]

Answer:

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A

Step-by-step explanation:

We are given the following in the question:

Product A:

Number of people,

$n_1 = 50$

Number of people who received relief,

$x_1 = 11$

Proportion of people who received relief from product A =

$p_A = \dfrac{x_1}{n_1} = \dfrac{11}{50} = 0.22 = 22\%$

Proportion of people who did not received relief from product A =

$1 = p_A = 1 - 0.22 = 0.78 =78\%$

Product B:

Number of people,

$n_2 = 100$

Number of people who received relief,

$x_2 = 14$

Proportion of people who received relief from product B =

$p_B = \dfrac{x_2}{n_2} = \dfrac{14}{100} = 0.14 =14\%$

Proportion of people who did not received relief from product B =

$1 = p_B = 1 - 0.14 = 0.86=86\%$

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A
