Answer:

$ 17.85

Step-by-step explanation:

Regular price = $ 21

Reduction = 15% of regular price

                 = \frac{15}{100}*21\\\\= 0.15*21\\= 3.15

                 = $ 3.15

Price of the item after reduction = 21 - 3.15 = $ 17.85

Helen [10]
Manufacturing cost = $136
sellers added 25% = $ 136 * 25/100 = $34 
manufacturers cost + 25% = $136 + $34 = $170. 
old selling price = $170

Sellers decreased the markup to 17% (of manufacturing cost): $136 x 17/100  = $23.12
New selling price = $136 + $23.12 = $153.12

both of these answers show: original cost + markup value

HELP ME RN PLZ
elena-14-01-66 [18.8K]

Answer:

200

Step-by-step explanation:

The reason why this answer is 200 is because it gave us a clue that 30 students said that pie was their favorite desert, what is half of 30? 15 so therefore, the pattern is half of each.

Ice cream: 35x2=70

Cake: 27x2=54

Candy: 23x2=46

Pie: 15x2=30

So, 70+54+46+30=200
