A store manager adjusts the price of an item each week that the item goes unsold. The price of the unsold item, in dollars, after x weeks can be modeled by the exponential function f(x) = 320(0.90)^x. The initial price of the item before the store manager made any adjustments was ​ ​ ​ (a)   . The price of the item​ ​ (b)   at a rate of ​ (c)   each week.

An artist bought a set of 10 paintbrushes that contained x small paintbrushes and y large paintbrushes. The number of small paintbrushes in the set was 4 times the number of large paintbrushes in the set. Which system of equations can be used to find the numbers of small paintbrushes and large paintbrushes in the set?

• x + y = 10

  x = 4y

• x - y = 10

  x = 4y

• x + y = 10

  y = 4x

• x - y = 10

  y = 4x
