The price of a desktop computer decreases from $1360 to $1020. Find the percentage decrease in its price

-20% discount

Step-by-step explanation:

subtract the two numbers:

1020-1360= -340 (is a percentage reduction, so I have to subtract the larger number from the smaller one)

divide the result by the original value:

-340÷1360= -0,25

to turn it into a percentage, multiply it by 100:

-0,25×100= -25%

23

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
