So the original price is "x".
the discounted price by 10% is P(x) = 0.9x.
the price minus a $150 coupon is C(x) = x - 150.
so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.
C( P(x) ) = P(x) - 150
C( P(x) ) = 0.9x - 150

Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
(you do the exact same you'd do in an equation problem. Get x by itself)
3x+1<2x-2<5x+7
1 < -x-2 < 5x+7
3< -x < 5x+9
3 < -6x < 9
-(1/2) > x > -(3/2)
x can't be bigger than -3 halves and be smaller than -1 half, so the answer is no solution
The product of x and 6: 6(x)
is at least -17: ≥ 17
6x ≥ 17 is your answer
hope this helps
