<h3><u>Question:</u></h3>

Jody is buying a scrap book and designed paper she has 40 dollars and needs at least 18.25 to buy a scrap book each seet of paper cost 0.34 how may sheets of paper can she buy

<h3><u>Answer:</u></h3>

Jody can buy 63 sheets of paper

<h3><u>Solution:</u></h3>

Jody has 40 dollars

Thus, she can spend less than or equal to 40 dollars

She needs at least 18.25 to buy a scrap book

Each seet of paper cost 0.34

Let "s" be the number of sheets of paper

Then,

$18.25+0.34s\leq 40\\\\Subtract\ 18.25\ from\ both\ sides\\\\0.34s \leq 40-18.25\\\\0.34s\leq 21.75\\\\Divide\ both\ sides\ by\ 0.34\\\\s\leq 63.9$

Thus Jody can buy 63 sheets of paper
