Respuesta :

The number of quarters Ella has is 19 quarters

Let

the number of dimes = x

The number of quarters = x + 6

Therefore,

Total number of coins:

  • 2x + 6

Total cost of the coins:

  • 0.1(x) + 0.25(x + 6)
  • 0.1x + 0.25x + 1.5
  • 0.35x + 1.5

Therefore,

0.35x + 1.5 = 6.05

0.35x = 6.05 - 1.5

0.35x = 4.55

x = 4.55 / 0.35

x = 13

Therefore, the number of quarters Ella has is 13 + 6 = 19 quarters
