Layala and Zahra have 2700 marbles in the ratio of 2:7. How many marbles Zahra must have gave away so that they both would have the same number of marbles?

1500

Step-by-step explanation:

Given that :

Total number of marbles held by Layala and Zahra = 2700

Ratio = 2 : 7

Layala's share of marbles : (2 / (2+7)) * 2700

= 2/9 * 2700

= 600

Zahra's share of marble : (7 / (2+ 7)) * 2700

= 7 / 9 * 2700

= 2100

Hence, Zahra must have given away (2100 - x) = 600

2100 - 600

= 1500 marbles, so that both Zahra and Layala have the same number of marbles

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.
