If tammy takes 200 steps to travel 1/4 of a city block, how many steps will she take to travel 4 3/4 city blocks?

4.75/0.25=19

200*19=3800

It will take Tammy 3800 steps

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
