Answer: 72 pesos.
Step-by-step explanation:
Supongamos que al principio tenias X, donde X representa la cantidad de dinero que tenias en un principio.
Gastaste:
X/3 en comida
X/8 en pasaje.
Entonces el gasto total es:
X/3 + X/8 = X*(1/3 + 1/8) = X*(11/24)
Entonces el dinero que te queda es:
X - X*(11/24) = X*(13/24) = 39 pesos.
X = (24/13)*39 pesos = 72 pesos
Al principio tenias 72 pesos.
Answer:
56 total
Step-by-step explanation:
Let the number of girls = x
Let the number of boys = 3x
x 1
=== = ==========
x + 28 3
Cross multiply
3x = x + 28 Subtract x from both sides
3x - x = 28 Combine
2x = 28 Divide by 2
x = 28/2
x = 14
Girls = 14
Boys = 14 + 28 = 42
Is the ratio 3 to 1?
42/14 = 3/1 Yes it does
Total number
14 + 42 = 56
When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.
Because 10,000 has 5 0's, we move the decimal 5 places to the right.
8.88 => 88800
