Answer: Sally paid less
Step-by-step explanation:
From the question, Sally paid $1.50 for 2 1/2 pounds of apples at the Grocery Mart. The cost per pound of apple will be:
= $1.50 ÷ 2 1/2
= $1.50 / 2.5
= $0.6 pee pound of apple
Fred paid $1.95 for 3 pounds of apples at the Corner Fruit Stand. The cost per pound of apple will be:
= $1.95 / 3
= $0.65 pee pound of apple.

Answer: x < -15
Step-by-step explanation:
(-2)*(x) > 30
x < -15 The inequality reverses direction when a negative number is used in the manipulation (we divided by -2).
A) n(0) = 20 because n(0) = 20(2)^0 and anything to the power 0 is 1. The reason that any number to the zero power is 1 is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1
Thus, n(0) = 20(1) = 20. In terms of the situation, if 0 days have passed since Monday, 20 people know about the rumor.
b) n(-2) = 20(2)^-2 = 20* 1/(2^2)
=20/(2^2) = 20/4 = 5.
In terms of the situation, two days before Monday, 5 people know the rumor.
