Answer:
$104 in the store
Step-by-step explanation:
To find the original cost <u>before</u> the discount, you divide the discounted price by the percentage, getting 104.
$104
If the cost in the store is x we can write:
75%x = 78
0.75x = 78
x = 78 / 0.75 = 104
3y+7=2x
3y=2x-7
y=(2/3)x-7/3
when parallel, the y=ax+b, the a keeps the same
so it‘s y=(2/3)x-a
and it pass (2,6), so 6=(2/3)*2 -a
6=4/3-a
-a=(18-4)/3
-a=14/3
a=-14/3
