A car dealership marks up all new automobiles by 15%. What was the original wholesale cost of a car with a sticker price of $22,500 at this dealership?

$19,565.22

Step-by-step explanation:

15% of 22,500 = 3375 as we multiply by 0.15

but, 15% of an initial is still whole 1 + 0.15  = 1.15 but when using sale prices to find initial we DIVIDE

= 22500 / 1.15 = 19565.2174

and round up by 2dp currency.

= $19565.22

The way to remember is the opposite finds the original

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
