you can spend at most $20 on tomatoes and red peppers for a soup. tomatoes cost $2.50 per pound and red peppers cost $4 per poun
Ber [7]

<u>Answer-</u>

\boxed{\boxed{2.50x+4y\leq 20}}

<u>Solution-</u>

The total money that you have or maximum amount that you can spend = $20

Let's assume,

x = Number of tomatoes bought

y = Number of red peppers bought

Price of tomatoes per pound = $2.50

Price of red peppers per pound = $4

Hence,

Total cost of tomatoes = $2.5x

Total cost of red peppers = $4y

As you can spend at most (any amount less than or equal to) $20, so

2.5x+4y\leq 20  

Taking a point as origin (0, 0) and then putting it in the equation,

\Rightarrow 2.5(0)+4(0)\leq 20\\\\\Rightarrow 0\leq 20

As this satisfies, so the shaded region will be towards that point i.e origin

Bobby describes two lines to Frank, telling him that beginning at point A, line #1 goes up 3 units and to the right 8 units, whi
rodikova [14]

When a line changes position from one point to another, the movement is referred to as transition.

<em>Bobby does not have enough information to make a valid conclusion.</em>

The movements of the lines are given as:

<em>Line 1: 3 units up and 8 units right</em>

<em>Line 2: 8 units down and 3 units right</em>

The given information only describes the movement of both lines, but does not give details about the initial relationship between the lines.

<em>Hence, no valid conclusion can be made with the given information.</em>
