Answer:
Lauren will get $640 and Cara will get $560.
Explanation:
Given that:
Age of Lauren = 16
Age of Cara = 14
Ratio = 16 : 14
Amount given by their grandad = $1200
Let,
x be the number of times.
16x + 14x = 1200
30x = 1200
Dividing both sides by 30

Share of Lauren = 16x = 16*40 = $640
Share of Cara = 14x = 14*40 = $560
Hence,
Lauren will get $640 and Cara will get $560.
