Jeffery babysits for 4 dollars per hour, he also works as a math tutor for 7 dollars per hour. He is only allowed to work 13 hou

Oksana_A [137]

Given:

Jeffery babysits for 4 dollars per hour and works as a math tutor for 7 dollars per hour.

He is only allowed to work 13 hours total per week.

He wants to make at least 65 dollars.

To find:

The system of inequalities to represent this situation.

Solution:

Let x be the number of hours he babysits per week and y be the number of hours h works as a math tutor.

He is only allowed to work 13 hours total per week. It means sum of x and y must be less than or equal to 13.

$x+y\leq 13$

He wants to make at least 65 dollars. It means total earnings must be greater than or equal to 65.

$4x+7y\geq 65$

Number of hours can not be negative.

$x\geq 0, y\geq 0$ .

Therefore, the required system of inequalities contains some equations, $x+y\leq 13,4x+7y\geq 65$ and $x, y\geq 0$ .

Jesean buys a pizza for 20$ and 10 drinks. The drinks Cost the same amount. He spends 32$ on the pizza and the sodas together

ziro4ka [17]

Answer: See explanation

Step-by-step explanation:

Yiur question isn't complete but I believe that you want to know the price of the soda.

Let the price of the soda be represented by x.

Jesean buys a pizza for 20$ and 10 drinks. This will be: 20 + 10x

He spends 32$ on the pizza and the sodas together. This can be formed into an equation as:

20 + 10x = 32

10x = 32 - 20

10x = 12

x = 12/10

x = 1.2

Therefore, the soda cost $1.20 each
