You have a summer job that pays you $5.60 an hour you get $8.40 an hour for overtime how many hours of overtime must you work to
Shtirlitz [24]

The following given problem can be expressed in the form of:

E = 5.60 * T1 + 8.40 * T2

 

where,

E = total earning

T1 = normal hours worked

T2 = overtime hours

 

Assuming that the maximum T1 hours is 40 hours. Beyond that is considered overtime, therefore:

 

287 = 5.60 * 40 + 8.40 * T2

T2 = 7.5 hours

 

<span>Therefore 7.50 overtime hours is needed.</span>

1&lt;br /&gt;Questão 10 - Um capital aplicado a&lt;br /&gt;umos simples durante 2 anos, sob&lt;br /&gt;taxe de juros de 5% ao mê
Elden [556K]

Answer:

2.995 ou 35.940 (?)

Step-by-step explanation:

Não me lembro exatamente como fazer isso, vou mostrar duas maneiras diferentes de resolver isso.

Use a fórmula l = P * r * t

| = Juros

P = Principal

r = taxa

t = tempo

Para resolver isso, você terá que ... O principal é 29.950, a taxa é 5%, mas se tornará um decimal que é 0,05, e o tempo é 2 Coloque-o na forma de fórmula 29.950 * 0,05 * 2 = 2.995 em interesse

Ou .. Você usará a mesma fórmula, mas desta vez multiplique 0,05 por 12, pois há 12 meses em um ano que é 0,6, então ... 29.950 * 0,6 * 2 = 35.940 de juros

Espero que funcione!
