Account balance = $389.42 + $389.42 (0.032) (7)
$389.42 + $87.23 = $ $476.65 (answer)
So, 10%-7%=3%=$294
$294/3%=$9800
Answer: The cost price of the necklace is $9800.
Answer:
A = x⁵ + 13x³ - 9x² + 40x - 72
Step-by-step explanation:
The formula for the area of a rectangle is length X width, or A = lw.
Substitute the equations for the sides into the formula:
A = lw
A = (x² + 8)(x³ + 5x - 9) <= use the distributive property
A = x⁵ + 5x³ -9x² + 8x³ + 40x - 72 <= collect like terms
A = x⁵ + 13x³ - 9x² + 40x - 72
