(1 point)

$154.31

$251.59

$228.72

$189.74

$228.72

To calculate this, we can break down the amount Cory saves each month:

June: $20
July: $20 * 1.10 = $22
August: $22 * 1.10 = $24.20
September: $24.20 * 1.10 = $26.62
October: $26.62 * 1.10 = $29.28
November: $29.28 * 1.10 = $32.21
December: $32.21 * 1.10 = $35.43

Adding all these amounts together, we get:
$20 + $22 + $24.20 + $26.62 + $29.28 + $32.21 + $35.43 = $190.74

Therefore, Cory will have $190.74 at the end of December.
