Answer 1

Answer:

A. $350.00

Step-by-step explanation:

The expression for a store to purchase x pounds of raisin-nut mix is;

P(x) = 3.50 + $0.90^{x}$

Where: P(x) is the dollar amount per pound, and x is the number of pounds bought.

The total price for the store to purchase 100 pounds can be determined by;

since the pounds of raisin-nut mix to be bought in a single order is 100, then x = 100.

So that;

P(x) = 3.50 + $0.9^{100}$

      = 3.5 + 0.000026561

P(x) = 3.500026561

Thus to the nearest $0.01, then;

P(x) = $\frac{3.500026561}{0.01}$

      = $350.0026561

P(x) = $350.00
