Bow Valley Electronics sold a mini stereo set during a sale for $776.Determine the regular selling price of the set if the price of the set had been reduced by 1/4 of the original regular selling price.

A machine requires 4 hours to make a unit of Product A and 7 hours to make a unit of Product B.The machine operated for 810 hours producing a total of 150 units.How many units of Product B were produced?

Solve the following equation: 5x - 4 + 9 = -3x - 2 - 13

Solve and find the value of a,given 3a + 4(15-2a)= 20

Simplify: -3x(4 - 2b - 2b)

Simplify:

Solve: 2x + 5 = 7

Solve: 5(8x - 2)- 5(3x + 5)= 36

Solve: Q = for p

Evaluate P: P = for A = 752,R = 0.145,T =

Simplify: 2(a - 1)(7a - 3)- 3(6a - 2)(2a + 1)

Simplify:

Simplify: 4x - 3y - 4x - 2y

Evaluate s: s = ,where p = 3411.50,r = 0.0925,t = 75

Simplify: 60xy ÷ (-5xy)

Evaluate:

Compute:
