Answer:
15
Step-by-step explanation:
Given that the profit equation from selling x necklaces is
P = −x2 + 35x.
To make a profit of $300, the profit P = 300 then
300 = -x2 + 35x
x2 - 35x + 300 = 0
solve by factorization
x2 - 15x - 20x + 300 = 0
x(x - 15) - 20(x - 15) = 0
(x - 15)(x - 20) = 0
x - 15 = 0 or x - 20 = 0
x = 15 or 20
Since 20 is higher, the least number of her necklaces she must sell to make a profit of $300.00 is 15

Answer:
They need to buy 6 pairs of uniform pants so that they pay the same amount for their purchases
Step-by-step explanation:
Let x be the no. of pairs of uniform pants for which the total cost in both the cases will be same.
Case 1:
Cost of 1 pairs of uniform pants = $17.95 each
Cost of x pairs of uniform pants = $17.95x
Cost of sweater = $24.
Total cost = 24+17.95x
Case 2:
Cost of 1 pairs of uniform pants = $18.95
Cost of x pairs of uniform pants = $18.95x
Cost of sweater = $18
Total cost = 18+18.95x
ATQ
Hence they need to buy 6 pairs of uniform pants so that they pay the same amount for their purchases
