Adealer sold 200 pairs of gloves. some were sold at $6 per pair and the remainder were sold at $11 per pair. total receipts from this sale were $1,600. how many pairs of gloves did he sell at $6 each

120 pair were sold at $.

Step-by-step explanation:

Given dealer sold pairs of gloves.

Total receipts from sale were $.

Let be the number of pairs sold at $.

And will be the number of pairs sold at $.

So, number of pairs times amount of pairs of each $ and $ when added should give us total amount of sale.

The equation will be

Hence number of pair sold at $ is 120.

Answer is B. x^7 - 4x^5 + 2x^4 + 4x^3 - 10
Here are a few rules of order
1. X values are always first, then y values
2. The highest exponent within that variable goes first (x^7 comes before x^5)
3. Numbers come after variables
Don't let the coefficients trick you since they are irrelevant if the exponent is higher. Automatically we know that -10 goes last because it is just a number. Then, you just order the x's from highest to lowest.
