Marty wants to paint a box. he can choose to use either blue, green, yellow, or black paint. also, he can style the paint by painting with a brush, a roller, or a sponge. how many different combinations of color and painting method can marty choose?

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

30005

yes ok
