Ariana plans to use $260 less than three-fourths of savings to buy a car. If the purchase price of the car is 9,340, how much do
tangare [24]

She has $12,488 in savings

Step-by-step explanation:

Ariana plans to use $260 less than three-fourths of savings to buy a car.

If the purchase price of the car is 9,340, we need to find how much

she has in savings

To find the savings

  • Assume that she has $x in savings
  • Write an equation of x
  • Solve the equation to find x

∵ She has $x in savings

∵ She plans to use $260 less than three-fourths of savings

- Three-fourths means \frac{3}{4} and less than means subtract

∴ She plans to use \frac{3}{4} x - 26

∵ The purchase price of the car is 9,340

- Equate the expression of x by 9,340

∴ \frac{3}{4} x - 26 = 9,340

Now let us solve the equation

∵ \frac{3}{4} x - 26 = 9,340

- Add 26 to both sides

∴ \frac{3}{4} x = 9,366

- Divide both sides by \frac{3}{4}

∴ x = $12,488

She has $12,488 in savings
