Por medio de sistema de ecuaciones:

*adultos (a) = $400

*niños (b) = $150

total de entradas : a + b = 600 ecua 1

dinero recaudado:

400a + 150b = 196 250 ecua 2

operamos:

a + b = 600 ecua 1

400a + 150b = 196 250 ecua 2

--------------------------

(-150) a + b = 600

400a + 150b = 196 250

-----------------------

- 150a - 150b = -90 000

400a + 150b = 196 250

-----------------------

250a = 106 250

a = 106 250/250

a = 425 adultos

a + b = 600

425+b =600

b = 600-425

b = 175 niños

comprobacion:

400a + 150b = 196 250

400(425)+150(175)=196 250

170 000 + 26 250 = 196 250

196 250 = 196 250

A coffee shop sold 7 cups,3 pints, and 9 quarts of coffee. Express the number of cups of coffee sold in base 2
sweet-ann [11.9K]

Answer:

The total number of cups of coffee sold are 51 which can be expressed in base 2 as 110011.

Step-by-step explanation:

Considering the following information

  • 1 cup = 1 cup
  • 7 pints = 14 cups      ∵ 1 pint = 2 cups
  • 9 quarts = 36 cups    ∵ 1 quart = 4 cups

So, total number of cups will be = 51 cups

Converting 51 to the base 2

Divide  51 by 2 by repeatedly and observe remainder

\frac{51}{2}=25\quad \mathrm{Remainder}\quad \:1

\frac{25}{2}=12\quad \mathrm{Remainder}\quad \:1

\frac{12}{2}=6\quad \mathrm{Remainder}\quad \:0

\frac{6}{2}=3\quad \mathrm{Remainder}\quad \:0

\frac{3}{2}=1\quad \mathrm{Remainder}\quad \:1

\frac{1}{2}=0\quad \mathrm{Remainder}\quad \:1

Read and observe the remainder from top to bottom would yield 110011.

Therefore, the total number of cups of coffee sold are 51 which can be expressed in base 2 as 110011.
