Answer:
So the slope is -8/3
Step-by-step explanation:
to find the slope you have to use m = y2-y1/x2-x1
so lets plug in our numbers
m = - 4- 4/5-2
= -8/3
So the slope is -8/3
She bought it at a 15% discount because 15 percent of 40 is 6 and 40-6=34
The reason is the gotter of the right angle is 12
X = adults
Y = child
X+y=168
X=168-y
$10x + $7y = $1446
10(168-y) + 7y = 1446
1680 - 10y + 7y = 1446
-3 y = -234
Y = 78
X = 168-78
X = 90
$10*90 + $7*78 =
$900 + $546 = $1446
.7
because you need to get the original unit price which is 0.7 then multiply that by 1 and get your answer
