Answer:
The percentage increase in worker wages in hourly rate of pay is 16.5%
Step-by-step explanation:
Given as :
The Initial wages earn by worker = $ 5.15 per hour
The Final wages earn by worker = $ 6 per hour
Let The percentage increase in her hourly rate of pay = x %
Now, According to question
x % =
or, x = × 100
or, x = × 100
or, x = 0.165 × 100
∴ x = 16.5%
So , Percentage increase in wages = x = 16.5 %
Hence The percentage increase in worker wages in hourly rate of pay is 16.5% Answer
The rate at 14% and 5% are $12, 883 and $2191 respectively.
<h3>How to determine the rate</h3>Given that;
Invested amount = $ 15, 074 at 14% and 5%
Let rate at 14% = x
rate at 5% = y
We have rate at 9% exceeds that of 5% by $1694. 07
Hence,
0. 14x = 0. 05y + $1694. 07 ⇒ equation 1
x + y = $15, 074 ⇒ equation 2
Make 'x' the subject
x =
Substitute in equation 2
Expand the expression
Collect like terms
Make 'y' the subject
y =
y =
Substitute the value in equation 2
x + y = $15, 074
x = $15, 074 - y
x =
x = $12, 883
Therefore , the rate at 14% and 5% are $12, 883 and $2191 respectively.
