Down payment of the ford pickup truck = $1,900.
It is said that down payment amount $1,900 owes 75% of the selling price.
Therefore, 100-75 = 25% is the downpayment of total Selling price.
Let is assume selling price is $x.
According to problem,
25% of the selling price equals down payment amount $1,900.
Let us convert above statement into an equation.
25% of x is 1,900.
That is 25% x = 1,900.
25% could be written as 25/100 or 0.25.
So, the above equation would become
0.25x = 1,900.
Dividing both sides by 0.25, we get
0.75x/0.25 = 1,900/0.25
x=7600
So, the selling price would be $7600.
