Question 83351
First we need to select the 2 items which add upto less than 20.

Consider 12.99 + 4.99 = $17.98

adding 7% tax, we get,

17.98 * 1.07 = $19.2386

Thus Jake could buy either a cologne and a candle or earings and a candle with $20 not going over.

9)  candle and plant cost = 4.99 + 7.99

                          = $12.98

   adding 7% tax, we get,
    
   12.98 * 1.07 = $13.8886
