You started a dog walking business. You spent $37 in start up costs and charge $12 per hour of dog walking. How many hours must you walk to reach $107? Which equation represents the situation?
$12-$37h=$107

$37+$12h=$107

$37h+$12=$107

$12h-$37=$107

$12h-$37=$107

Step-by-step explanation:

multiply the amount of hours by 12 for money. But don't forget to the startup costs that will have to be subtracted from the finances before the final answer. The amount of hours you will have to do is 111.

step-by-step explanation:

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
