Question

Linda has $9.00 in her wallet. she buys a card for $1.17. she wants to buy some pens that cost $2.65. what is the maximum number of pens can she buy

Answer 1

2 pens

Explanation:

Let x represent the number of pens Linda buys. Since they cost $2.65 each, this gives us the expression 2.65x.

Adding the cost of the card to this gives us the expression 2.65x+1.17.

She has a total of $9.00; this gives us the equation

2.65x+1.17 = 9.00

Subtract 1.17 from each side:

2.65x+1.17-1.17 = 9.00-1.17

2.65x = 7.83

Divide both sides by 2.65:

2.65x/2.65 = 7.83/2.65

x = 2.95

We cannot buy a portion of a pen, so the most she can buy is 2 pens.

Answer 2

The answer is 2 pens.

Explanation:

Total amount Linda has in her wallet = $9

Amount spent on buying a card = $1.17

So, amount left with Linda =
`9-1.17=7.83`

Now, she wants to buy pens that cost $2.65, so the maximum number of pens she can buy are =
`(7.83)/(2.65)= 2.9`

But, pens cannot be in decimal, so the maximum pens she can buy are 2.
