You can you 72 which would make 2/8 18/72 and 3/9 24/72 which makes the sum 42/72.
Answer:
Terry's initial amount = £780
Step-by-step explanation:
Given that:
Ratio of Terry's money to Faye's money = 3 : 5
Let,
x be the amount of money.
Terry's amount = 3x
Faye's amount = 5x
Now,
3x + 220 = 5x - 300
220+300 = 5x - 3x
520 = 2x
2x = 520
Dividing both sides by 2

Terry's initial amount = 3x = 3(260) = £780
Hence,
Terry's initial amount = £780
85w + 350 ≥ 715
This is because you initially have 350 already, so that number shouldn't be altered. W represents the weeks, and since you get 85 per week, 85w would represent the end amount after a set amount of weeks.
Add that to the initial amount of 350.
It also states that you need at least 715, so you can have more. ≤ would represent less than or equal to, making any with that the incorrect answer.
Hope this helps!
