Sharon, planning a party, bought some compact discs, pizzas, ad helium-filled balloons. the cds cost $15 each, the pizzas cost s10 each, and the balloons cost $5 each. if she spent a total of s, how many cds, pizzas, and balloons did she buy?

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

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
