Step-by-step explanation:

The options were not given,en but the question can still be solved.

Given

Required

Determine the cost of 20 vases, 40 daises and 80 magnolias

If 1 vase costs $v, then

If 1 daises costs $x, then

If 1 magnolias costs $y, then

Another expression that represents the total is to factorize the expression.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

correct answer is b. 27/8
