Answer:
1) $343
2) $40
Step-by-step explanation:
1) Kathy paid (100 - 30)% of 490
so we can multiply 490 by 70%
490 x .7 = 343
2) let 'x' = original price
if she's saving 10% (or .10) then she's paying 90% (or .90)
.9x = 36
x = 36/.9
x = 40

Answer:
x=1.5
Step-by-step explanation:
We are trying to get x by itself to see what it equals.
6(2x+3)=36
So first you want to distribute you proprieties. You do that by multiplying 6 and 2x. Then multiplying 6 and 3.
12x+18=36
Now in equations where you need to find the variable, whatever you do on one side of the equal sign, you have to do on the other side. So now we want to subtract 18 from both sides.
12x+18=36
-18 -18
Then we divide 12 from both sides.
12x=18
÷12 ÷12
Now you have your answer!
x=1.5
