An arrangement of flowers originally priced at $48.00 is marked down to $39.00. what is the percent of decrease, rounded to the nearest whole number?

To find the percentage of decrease, use this formula.

Percentage decrease=  old amount- new amount

                                               old amount

So subtract 48 by 39 which is 9.

Divide it by 48, which is  0.1875.

DO NOT STOP THERE! Multiply that by 100 to get the percent amount, then round it off, which is 19%.

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
