1. For part (a), round each price to the nearest dollar:
   - $$ \$4.87 $$ rounds to $$ \$5 $$,
   - $$ \$5.19 $$ rounds to $$ \$5 $$,
   - $$ \$6.01 $$ rounds to $$ \$6 $$,
   - $$ \$6.39 $$ rounds to $$ \$6 $$,
   - $$ \$6.29 $$ rounds to $$ \$6 $$,
   - $$ \$8.36 $$ rounds to $$ \$8 $$.

Adding these rounded values:
   $$
   5 + 5 + 6 + 6 + 6 + 8 = 36
   $$
   So, the approximate total cost is $$ \$36 $$.

2. For part (b), if you do not buy the last item (priced $$ \$8.36 $$ which rounds to $$ \$8 $$), then the rounded sum of the remaining five items is:
   $$
   5 + 5 + 6 + 6 + 6 = 28
   $$
   With $$ \$40 $$ available, the change you would receive is:
   $$
   40 - 28 = 12
   $$
   So, the approximate change is $$ \$12 $$.

(a) $$ \$36 $$  
(b) $$ \$12 $$
(a) The total cost is approximately \$36. (b) The change will be approximately \$12.
