For Judy's birthday, her friend gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clot
vladimir1956 [14]

Answer:

<h3>The percentage is <u>60%</u> of the total amount paid with the gift card. </h3>

Step-by-step explanation:

Given:

Total worth of clothing is $178.25 and the amount paid with cash is $71.30.

Let us find the part of amount  paid with the gift card:

Amount of gift card(G) = Total worth(T) - Amount paid in cash(C).

G\ =\ 178.25-71.30

G\ =\ 106.95.

So, the amount paid with the gift card is $106.95.

Now, according to question:

\frac{106.95}{178.25}\times100

=0.6\times100

=60%.

Therefore, the percentage is <u>60%</u> of the total amount paid with the gift card.

Find two numbers if their sum is 6.1 and their difference is 1.6
Radda [10]
For this case, the first thing we must do is define variables:
 x: unknown number (1)
 y: unknown number (2)
 We now write the equations that model the problem:
 their sum is 6.1:
 x + y = 6.1&#10;
 their difference is 1.6:
 x - y = 1.6&#10;
 Solving the system we have:
 We add both equations:
 x + x = 6.1 + 1.6&#10;&#10;2x = 7.7&#10;&#10;x = 7.7 / 2&#10;&#10;x = 3.85
 Then, we look for the value of y using any of the equations:
 x - y = 1.6&#10;&#10;y = x - 1.6&#10;&#10;y = 3.85 - 1.6&#10;&#10;y = 2.25
 Answer:
 
The numbers are:
 
x = 3.85&#10;&#10;y = 2.25
