The price of a car was decreased by 16% to £2400. What was the price before the decrease?

£2857.14

Step-by-step explanation:

Given parameters:

Cost of car  = £2400

 Discount  = 16%

Unknown:

The original cost  = ?

Solution:

 Original price - ( 16%  x original price) = New price

   Original price(1 -  16% ) = 2400

   Original price(1 - 0.16) = 2400

    Original price x 0.84 = 2400

    Original price  =   = £2857.14

answer: a

step-by-step explanation:

10.2 units

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
