Question

A worker's period of duty increases from 56 hours to 72 hours but the wages decreases by 15 percent. By what percentage do the new total wages increase or decrease

​

Answer 1

Based on the given conditions, formulate:

`(72-56-15\%*72)/56`

Calculate the product or quotient:

`(72-56-10.8)/(56)`

Calculate the sum or difference:

`(16-10.8)/(56)`

Calculate the sum or difference:

`(5.2)/(56)`

Convert decimal to fraction:

`(52)/((10)/(56) )`

Divide a fraction by multiplying is reciprocal:

`(52)/(10)* (1)/(56)`

Reduce the expression to the lowest term:

`(13)/(5) *(1)/(28)`

Write as a single fraction:

`(13)/(5*28)`

Calculate the product or quotient:

`(13)/(140)`

Rewrite the fraction as a decimal:

`0.092857`

Multiply a number both the numerator and denominator:

`0.092857*(100)/(100)`

Write as a single fraction:

`(0.092857*100)/(100)`

Calculate the product or quotient:

`(9.2857)/(100)`

Rewrite a fraction with denominator equals 100 to a percentage:

`9.2857\%`

Answer:

`\longrightarrow9.2857\%`
