Answer:
Only if there 10 students, which isnt likely
Step-by-step explanation:
The slope of the line is .75 or 3/4
Write their age ratio
E : F : G = 9 : 13 : 18
From the ratio above, we know that the sum of the ratio is
9 + 13 + 18 = 40
Count their money
For Eli, the ratio is 9
Eli's money = Eli's ratio/the sum of ratio × the sum of money
Eli's money = 9/40 × 800
Eli's money = 180
For Freda, the ratio is 13
Freda's money = Freda's ratio/the sum of ratio × the sum of money
Freda's money = 13/40 × 800
Freda's money = 260
For Geoff, the ratio is 18
Geoff's money = Geoff's ratio/the sum of ratio × the sum of money
Geoff's money = 18/40 × 800
Geoff's money = 360
So the answer:
Eli = £180
Freda = £260
Geoff = £360
