An Iphone 6S costs $449. There is a discount of 15%. What is the new cost?

$381.65

Step-by-step explanation:

Multiply $449 by 0.15, then subtract your answer from the original number.

The new cost is $381.65.

Step-by-step explanation:

Since you have a discount of 15%, you are only paying 85% of the original cost.

100%-15%=85%

85%=85/100=0.85

To find 85% of the original price, multiply 0.85 to 449.

0.85(449)=381.65

Don’t forget units!

$381.65

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
