1) Venta con ganancia
Precio de venta 60 soles.
Ganancia = 20% del costo => costo + 0,20 * costo = precio
=> costo (1 + 0,20) = precio = 60 soles
=> costo (1,20) = 60 soles => costo = 60 soles / 1,20 = 50 soles
2) Venta con pérdida del 20%
Pérdida = 20% del costo
=> costo - precio = 20% * costo => costo - 0,20*costo = precio
=> costo ( 1 - 0,20) = 60 soles => costo * 0,80 = 60 soles
=> costo = 60 soles / 0,80 = 75 soles
3) Costo total = 50 soles + 75 soles = 125 soles
4) Ganancia total = valor total de venta - costo total
Ganancia total = 2 * 60 soles + 125 soles = 120 soles - 125 soles = - 5 soles.
El signo negativo significa que al final se perdió 5 soles en la operación.
Answer:
<u>The four employees earned $ 452.80 in total</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Hour rate = $ 8.20
Overtime hour rate = $ 2.20 extra
Regular hours = 10
Overtime hours = 3
Number of employees = 4
2. How much money did they earn in total?
Let's find out the individual pay for an employee and then we'll calculate the pay for the 4 employees:
Individual pay = 10 * 8.20 + 3 * 10.40
Individual pay = $ 113.20
Total pay = Individual pay * 4
Total pay = 113.20 * 4
<u>Total pay = $ 452.80 </u>
65÷455= 7
Hope this helps!
