A grocery store offers a coupon for $2 off when a customer buys 6 or more bottles of water. The water costs $1.75 per bottle. Shauna uses the function ( ) = 1.75 − 2 to find the total dollars it costs to buy bottles of water. When she uses the function to find how many bottles she can buy for $5, she finds b ≈ 3.4 , so she concludes she could buy 3 bottles of water for $5. Explain what error Shauna made.
