Question

Robert has no more than $\$35$. He wants to buy at least two pairs of jeans for $\$15$ each and one t-shirt for $\$5$. Is there any deficit of money?

• A. Yes
• B. No

Answer 1

The correct option is B No

Let $x$ represent the amount of money Robert had and $y$ represent the cost of all the items to be bought.

Given,
$x\le \$35$
A closed circle at $35$ and the red line goes to the left, indicating that $x$ is less than or equal to $35.$

Cost of two pairs of jeans $=2\times 15=\$30$
Cost of 1 t-shirt $=\$5$

He wants to buy at least two pairs of jeans and 1 t-shirt.
$y$ $\ge$ Cost of 2 jeans + Cost of 1 tshirt
$y\ge 30+5$
$y\ge \$35$

A closed circle at $35$ and the red line goes to the right, indicating that $x$ is greater than or equal to $35.$

As $x$ is equal to $y$ at $35, Hence there will be no deficit of money.
