Answer:
The correct answer is 18
the correct expression is
Step-by-step explanation:
let the number be n
therefore if he is required to multiply n by 4 and added to 6 we have
given that he did otherwise by adding 6 to n and multiply by 4 we have
Firstly we need to solve for n in equation 2
Dividing both sides by 4 we have
In order to solve for the correct answer let us input n=3 in equation 1 we have
11 is your answer because 11* 11 is 121
Answer:
$331.25
Step-by-step explanation:
Given:
The jewelry center bought a pair of earrings for $250
They are going to mark the price of the earrings up 32.5%
