Plz answer i need help

480

Step-by-step explanation:

We can set up a proportion:

#students that eat carrots / #students surveyed=#students that eat carrots / #students surveyed

x will equal the number of students in Sarah's school who eat carrots.

30/50 = x/800

We can simplify

3/5=x/800

We cross multiply

5x=3*800

5x=2400

x=480

Hope this helps!

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
