2300 is invested in 4 years at 5% per year simple interest work out the total interest

460

Step-by-step explanation:

I=P x r x t

P is the principal amount, $2300.00.

r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.

t is the time involved, 4year(s) time periods.

So, t is 4year time periods.

To find the simple interest, we multiply 2300 × 0.05 × 4 to get that:

The interest is: $460.00

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

its an acute right triangle
