Answer 2

Answer:

Please see the attachment for graph.

Step-by-step explanation:

Toby is buying apples. Red delicious apples and Braeburn apples.

Let x pounds of Red Delicious apple and y pound of Braeburn apples.

Cost of 1 pound of Red delicious apple = $2

Cost of x pound of Red delicious apple = 2x

Cost of 1 pound of Braeburn apple = $3

Cost of y pound of Braeburn apple = 3y

According to question:

He wants to buy at least 10 pounds of apples

Therefore,  x+y≥10

He spends no more than $24

Therefore, 2x+3y≤24

We get two inequality

x+y≥10

2x+3y≤24

Now we draw the graph of both inequality

We make table of x and y of both equation

Table 1: x+y≥10

x       0     6       10

y      10     4       0

Test point (0,0). We get FALSE. Shaded portion away from origin.

Table 2: 2x+3y≤24

x       0     6     12  

y      8      4      0

Test point (0,0). We get TRUE. Shaded potion towards origin.
