Properties of Real Numbers · Exercise 97

Buying by the case Trader Joe’s grocery stores sold a bottle of wine they called “Two Buck Chuck” for $1.99. They sold a case of 12 bottles for $23.88. To find the cost of 12 bottles at $1.99, notice that 1.99 is $2-\mathrm{0.01.}$

ⓐ Multiply 12(1.99) by using the distributive property to multiply $12\left(2-0.01\right).$
ⓑ Was it a bargain to buy “Two Buck Chuck” by the case?
