plzz help I am doing a Unit Test!.
Sure, no problem. If you need any help, just let me know.
First, find the cost of one light bulb:
$9/5 = $1.80
Then, multiply the cost of one light bulb by 7:
$1.80 x 7 = $12.60
Therefore, 7 light bulbs would cost $12.60.

2. Sophie Ruth is eating a 50- gram chocolate bar which contains 30% cocoa.
How many grams of cocoa are in the chocolate bar?
To find out how many grams of cocoa Sophie's chocolate bar contains, multiply the grams of the chocolate by the percentage of cocoa:
50 grams x 30% = (50 x 30) / 100 = 15 grams
Therefore, there are 15 grams of cocoa in Sophie's chocolate bar.
