McKayla wants to rent a surf board this Saturday. She looks up the price to rent one and finds that it costs $45 per hour to rent the board and $18 for the oil to clean the surfboard after she uses it. Create an expression to model how much McKayla will spend to rent a surfboard for x hours and oil the board

45x + 18

Step-by-step explanation:

I believe this is the answer because x is the number of hours McKayla rents the surf board and it's $45 for every hour, no matter how many hours she rents she'll have to pay $18.

(sorry i'm not that great in explaining)

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

the answer is 13/48
