Answer:
21.
Step-by-step explanation:
f(x) = 2x^2 - 3x + 7.
When x = -2,
f(-2) = 2(-2)^2 - 3(-2) + 7
= 2(4) - (-6) + 7
= 8 + 6 + 7
= 21.
Just simply add
22+6.80= 28.80
So now the selling price is $28.80
Answer:
$42.5
Step-by-step explanation:
Find how much is 15% of 50 first
(15/100)×50=$7.5
$7.5 is the amount that will be discounted so
$50(original price)-$7.5(discount)=$42.5
