Answer:
The prince's crown had a greater ratio of red gems to purple gems.
Step-by-step explanation:
KING = 5 red / 8 purple
PRINCE = 4 red / 5 purple
Times the ratio for the king by 5
5(5) / 8(5) = 25/40
Times the ratio for the prince by 8
4(8) / 5(8) = 32/40
The prince has a greater ratio of red gems
Hope this is right, and sorry if it is incorrect. Have a good day!

Answer: x ≥ 5
Step-by-step explanation:
7 is increased by the product of a number and 3: 7 + 3x

3x ≥ 15
divide both sides by 3
x ≥ 5
Answer:
$2000
Step-by-step explanation:
let x be the money she invested
lets assume this was for 1 year
0.09(x/2) + 0.07(x/2) = 160
multiply each side by 2 to cancel the denominators:
0.09x + 0.07x = 320
0.16x = 320
x = 2000
