Let x equal the number of adult tickets sold.
X + 3X=512
(I put 3x because we know the students sold 3 times as many).
Solve for X.
X+3X=512
4X=512
4X/4=512/4
X=128
Answer:
la probabilidad es 1/11
Step-by-step explanation:
Hay 4+4+4 = 12 canicas en total en la bolsa.
Pues la posibilidad de sacar una canica azul en el principio es 4/12 o 1/3.
Y luego, no reemplaces la canica, y hay 11 canicas en total.
Por eso la posibilidad de sacar otra canica azul después es 3/11.
Son eventos independientes, y tenemos que multiplicarlos para tener la respuesta.
1/3 * 3/11 = 1/11
Answer:
option: D is correct. ( (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).
Step-by-step explanation:
" Markup is the percentage difference between a product's cost and its selling price "
Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.
As there is a markup of 15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.
<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>
<em>Hence, option D is true.</em>
