Three business partners, A, B and C, share the profits as follows: The ratio of A's share to B's share is 6:5 and the ratio of B's share to C's share is 3:4. Determine:
5.1 A's share:B's share:C's Share.
5.2 the total profit if A gets $5000 less than C.

b. astronomers

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
