Question

The table shows the price of some laptop computers.Rebecca wants to spend no more than $450 for a new computer.

Answer 1

Answer:

Part A) The inequality that represent this situation is equal to

$p\leq \ 450$

Part B) Computer A, Computer B,

Step-by-step explanation:

Part A)

Let

p------> the price of a new laptop computer

we know that

The inequality that represent this situation is equal to

$p\leq \ 450$

Part B)

we know that

If a price is a solution of the inequality, then the price must satisfy the inequality

Verify each case

case A) For $p=\ 419$

Substitute the value of p in the inequality and then compare

$\ 419\leq \ 450$ ------> is true

therefore

Rebecca can buy computer A

case B) For $p=\ 450$

Substitute the value of p in the inequality and then compare

$\ 450\leq \ 450$ ------> is true

therefore

Rebecca can buy computer B

case C) For $p=\ 468$

Substitute the value of p in the inequality and then compare

$\ 468\leq \ 450$ ------> is not true

therefore

Rebecca cannot buy computer C

case D) For $p=\ 451$

Substitute the value of p in the inequality and then compare

$\ 451\leq \ 450$ ------> is not true

therefore

Rebecca cannot buy computer D
