Joel divided 68 cds evenly on 4 shelves in his bedroom. the cds are arranged in alphabetical order, with the first shelf containing the letters a-e. if there are 13 cds filed under a-d, how many cds are filed under the letter e?

4

Step-by-step explanation:

Given:- Total cds = 68

Total shelves=4

If cds are evenly on 4 shelves then, to find the the number of cds in 1 shelf, we need to divide total cds by total shelves.

Thus, the number of cds in 1 shelf=

If the first shelf containing the letters a-e. if there are 13 cds filed under a-d,

then cds filled under the letter e= 17-13=4

Therefore, cds filled under the letter e=4

were is the equation

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
