<h2>the original number is 38</h2>
Step-by-step explanation:
Let the two-digit number be 10t+u where t is the tens digit and u the units digit.
-------------------
EQUATION:
t+u = 11
10u+t = 10t+u + 45
-------------
Rearrange the equations:
t+u = 11
9t-9u = -45
-------------
Simplify:
t+u = 11
t-u = -5
---------
Add the equations to solve for "t":
2t = 6
t = 3
--------
Substitute to solve for "u":
3+u = 11
u = 8
Answer:
$171
Step-by-step explanation:
A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?
Let x represent the original price of the pair of pants
From the question, we know that:
10% of x = $17.10
10/100 × x = $17.10
10x/100 = $17.10
Cross Multiply
10x = 100 × $17.10
10x = 1710
x = 1710/10
x = $171
Hence, the original price of the pants = $171
For 5% you would have to pay 5,250 4% 5,200
