I think it is .8 i could be wrong i’m not sure
#15(A)
First Bike
$380 - $190 ($380 * 0.50) = $190
2nd Bike
$380 - $114 ( $380 * 0.30) = $266
$266 - $53.20 ($266 * 0.20) = $212.80
#15 (B)
Eliza should buy the first bike because it is cheaper. $190 < $212.80
#16
$57 + $28.50 ($57 * .50) = $85.50
Answer:
B. 27.5
Step-by-step explanation:
1/2 (b x h)
B (Base) = 11
H (Height) = 5
1/2 (11 x 5)= 27.5
Y-INT IS $100 since its the starting point. 20 is the slope so make graph counting by 20’s
Step-by-step explanation:
To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: 
Solving for y:
because
or 
So on interchanging the variable, we get the equation:
