Joe is 1.6m tall. his shadow is 2m long when he stands 3m from the base of a floodlight.
height
1.6 m
2m
3m
what is the height of the floodlight?
2.4 m 2.6 m 4.0 m 4.2 m

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
