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 t (b) = 1.75b – 2 to find the total t dollars it costs to buy b 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.
