Let f be the height of the fir trees
Let p be the height of the pine trees
We know from the problem that
f + p = 21 and 4f = 24 + p
rearrange the 2nd equation to get p = 4f - 24 and substitute into the other equation
so...
f + 4f - 24 = 21
5f - 24 = 21
5f = 45
f = 9 - height of the fir tree
substitute back into the 1st equation
9 + p = 21
p = 12 - height of the pine tree

Answer:The total cost for the car including tax is $27423.75
Step-by-step explanation:
The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be
6.5/100 × 25750 = 0.065 × 25750 = 1673.75
The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes
25750 + 1673.75 = $27423.75
