Answer:
It is cheaper to buy bulbs from Beautiful Bulbs at 6 for $3.54 than it is to buy them from Bright Bulbs at 4 for $2.48.
Explanation:
To check which deal is better, find how much it costs per bulb with each deal. To do this, divide the price by the amount of bulbs.
Bright Bulbs: 2.58 ÷ 4 = 0.62
It costs 62¢ per bulb if you buy them using Bright Bulbs.
Beautiful Bulbs: 3.54 ÷ 6 = 0.59
It costs 59¢ per bulb if you buy them using Beautiful Bulbs.
0.59 is less than 0.62, so bulbs are cheaper at Beautiful Bulbs.
