Accepted Solution

A:

Answer:$54,000Amount of discount = $88.02The new price = $978 - $88.02 = $889.98Length of shorter piece is 1 ft and longer piece is 5 ft
Step-by-step explanation:Given:Raise received = 3%New salary = $55,620Now, New salary = old salary + 3% of old salary or$55,620 = old salary + (0.03 × old salary) or$55,620 = Old salary × (1.03)or
Old salary = $54,000
Given:Price of the new fridge = $978Discount offered = 9%Thus, Amount of discount = 9% of $978orAmount of discount = 0.09 × $978orAmount of discount = $88.02And, the new price = Price of the fridge - Amount of discount orThe new price = $978 - $88.02 = $889.98Given:Length of the of the board before cutting = 6 ftNow, According to the questionlet the length of the shorter piece be 'x'thus, 6 = x + (3x + 2)or6 = 4x + 2or4 = 4xorx = 1 fthence, shorter piece is 1 ft long and longer piece is (3x +2 = 5ft)
