Answer:
<em>$111.95 or $84.95</em>
Step-by-step explanation:
The second skateboard cost either $13.50 ,more than $98.45 or $13.50 less than $98.45.
Add $13.50 to %98.50, and then subtract $13.50 from $98.45.
$98.45 + $13.50 = $111.95
$98.45 - $13.50 = $84.95
Answer:
у = x² + 7x - 30
Step-by-step explanation:
x₁ = 3 and x₂ = -10
Use the formula (x - x₁)(x - x₂) = 0
(x - 3)(x - (-10)) = 0
(x - 3)(x + 10) = 0
x² + 10x - 3x - 30 = 0
x² + 7x - 30 = 0
You can start by converting from degrees to radians and using the relation

Or just set up the proportion equation,
She got back $6.50.
explanation -
30 x 1.45 = 43.5
50 - 43.5 = 6.50
