Bellas cell phone costs $18 per month plus $0.15 for every minute she uses the phone . last month her bill was 29.25. for how many minutes did she use her phone last month?

75 minutes

Step-by-step explanation:

Sorry my answer was late, I started this question but had received a phone call.

29.25-18 = 11.25

11.25/.15 =75

where's the diagrams?

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
