A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year

Andru [333]

Answer:

$y = 18 * 1.15^x$

Step-by-step explanation:

Given

$a = 18$ --- initial

$r =15\%$ -- rate

Value after a year = $20.70

Required

Expression to calculate its value after y years

This is calculated using:

$y = ab^x$

Where

$b=1 +r$

Substitute $r =15\%$ in $b=1 +r$

$b = 1 + 15\%$

$b = 1 + 0.15$

$b = 1.15$

Substitute $b = 1.15$ and $a = 18$ in $y = ab^x$

$y = 18 * 1.15^x$

natta225 [31]

Answer:

7/4 yard

Step-by-step explanation:

36 is a suitable common denominator for expressing these fractions. All measures are in yards.

2/3 + 4/9 + 23/36 = (12·2)/(12·3) + (4·4)/(4·9) + 23/36

= 24/36 + 16/36 + 23/36

= 63/36 = (9·7)/(9·4)

= 7/4 = 1 3/4 . . . . . yards
