kogti [31]

Answer:

$400

Step-by-step explanation:

Given that:

Earnings per week for Amber = $200

Total increase in the salary as per Amber's hard work = 100%

To find:

Earnings of Amber now?

Solution:

We are given the initial salary and its percentage increase.

We have to find the increased value of salary.

Increase in the salary = 100% of $200

\Rightarrow \dfrac{100}{100}\times \$200\\\Rightarrow \bold{\$200}

Amber's Current salary = Initial salary + Increase in the salary

Putting the values of the initial salary and increase in the salary:

Amber's Current salary = $200 + $200 = <em>$400</em>

Terry sees this offer refurbished phone 35% off now only ?78 what was the original price
Ronch [10]

Answer:

$223.

Step-by-step explanation:

Let x be the original price of phone.          

We are told that Terry sees this offer refurbished phone 35% off now only $78.

We need to find x such that 35% of x is 78. We can represent this information as:

\frac{35}{100} x=78

0.35 x=78

x=\frac{78}{0.35}    

x=222.8571428571428571\approx 223

Therefore, the original price of phone was $223.
