Arectangular garden of area 48 square feet is to be surrounded on three sides by a brick wall costing 20 dollars per foot, and on the fourth side by a fence costing 10 dollars per foot. find the smallest amount of money that can be spent on materials.

$484.97.

Step-by-step explanation:

For a minimum amount of wall/fencing the garden has to be a square.

That would make each side of the garden = √48 dollars.

So the smallest amount  would be √48 * 3 * 20 +√48 * 10

= $484.97.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
