Answer 2

Answer:

only two

Step-by-step explanation:

Jane went to the grocery store with $10 in her pocket.

She wants to purchase as many 12-packs of soda that she can.

One 12-pack soda costs = $3.20 and Sales tax = 8%

Cost of 12-pack soda with sales tax = 3.20 + (8% of 3.20)

                                                           = 3.20 + (0.08 × 3.20)

                                                           = 3.20 + 0.256

                                                           = $3.456

In $10 she can buy  = $\frac{10}{3.456}$ = 2.89

She can buy only two 12-packs of soda and money left with her $3.088.
