It cost $480 to rent apartment on the gold coat for a weekend.
last year. it cost $400.00.
what method do i use to calculate the % off increase?

answer:

you would find the difference of the prices and divide the value by the original price, the difference would be 80, 80/400 is 1/5 which is 20%. you could write a set of equations or use the interest formula, where p equals the principal amount. r equals the rate/ percentage of interest, n equals the compounding periods and t equals time. hope this ! : )

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
