The expression that signifies Katherine’s final cost F= P + T= $466
<h3>Calculation of final cost</h3>
The number of pansies to be arranged around each tree = 15 pansies
The cost of pansies(P) = 15 × 8 × 2.50 = $300
The number of juniper trees available = 8
The cost of the trees available(T) = 8 × 20.75= $166
Therefore Katherine's final cost(F)= $300 + $166 = $466
The expression to find Katherine’s final cost = F= P + T
