d) Cannot be determined

Answer 1

You paid less for the bottle this week by $0.50.

Step-by-step explanation:

To determine if you paid more or less for the bottle this week, we need to compare the cost of the bottle last week and this week. Last week, the cost of a bottle was $2. This week, the bottles are on sale for 4 for $6. If we divide the total cost by the number of bottles, we find that each bottle costs $6/4 = $1.50.

Comparing the prices, we see that the cost of the bottle this week is less than last week. You paid $2 for the bottle last week and $1.50 for the bottle this week, so you paid less by $2 - $1.50 = $0.50.

Therefore, you paid less for the bottle this week by $0.50.
