Answer:
No. Nezzie has taken successive discounts on the total, but the coupon is just on the playhouse.
Step-by-step explanation:
Nezzie buys a playhouse for $100.29 and a music center for $59.99.
After 10% off on playhouse, its price is = =$90.26
After 10% off on music center, its price is = =$53.99
She has a coupon for an additional 15% off on the playhouse. Means after the coupon, the price of the playhouse will be :
= $76.72
Nezzie estimates that her total, after discounts, will be about $122.
Her total in actual is = dollars
So, Nezzie did nor estimate correctly.
The correct option is -
No. Nezzie has taken successive discounts on the total, but the coupon is just on the playhouse.
Means first she subtracted 10% from the total amount (100.29+59.99) and then she subtracted 15% from it.
Total = 160.28
10% off =
15% off = =$122.6

We have 2 denominators that we need to get rid of. Whenever there are the denominators, all we have to do is multiply all whole equation with the denominators.
Our denominators are both 2 and x+1. Therefore, we multiply the whole equation by 2(x+1)
Then shorten the fractions.
Distribute in all.
We should get like this. Because the polynomial is 2-degree, I'd suggest you to move all terms to one place. Therefore, moving 2x+2 to another side and subtract.
We are almost there. All we have to do is, solving for x by factoring. (Although there are more than just factoring but factoring this polynomial is faster.)
Thus, the answer is x = 3, -2
