What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, you buy 1 balloon and 1 banner for $4. your friend buys 3 balloons and 2 banners for $9.
Let x represents balloons and y represents banners.
Establishing the equations,
x+y = 4
x = 4 - y......(i)
3x + 2y = 9...(ii)
Put eq(i) in eq(ii)
3(4 - y) + 2y = 9
12 - 3y + 2y = 9
y = 3
Put y = 3 in eq(i)
x = 4-3
x = 1
Hence, the costs of each balloon and banner are $1 and $3 respectively.

A small artichoke contains about 9 milligrams of vitamin C. It also contains about 15% of the recommended amount of vitamin C an average adult should get each day. About how many artichokes would an average adult have to eat in a day to get the necessary amount of vitamin C.
Answer:
7 Artichokes
Step-by-step explanation:
To figure this out, we need to find out how much Vitamin C an average adult needs. We set up a proportion.
[tex]\frac{9}{15} = \frac{x}{100}[/tex]
[tex]15x=900[/tex]
[tex]x=60[/tex]
Now, since each artichoke is worth 9 milligrams, we divide 60 by 9.
[tex]60/9=6.66666...[/tex]
So, to get the necessary amount of Vitamin C, we round up to 7.

Monica had a savings account that paid her an interest rate of 4%. After she had this account for 12 years, she had received $192 in interest. How much money had she put into the account at the beginning of the 12 years?
Answer:
Money she put in her account = $400
Step-by-step explanation:
As, to find the interest the formula is PTR/100 = I
Where P = Principcal
And T = time (in years)
And R = rate
And I = interest
So here p is not present we need to find it
R = 4%
And T = 12 years
And I = $192
= p x 4 x 12 /100 = 192
P x 4 x 12 = 19200
P x 48 = 19200
P = 19200/48
P = 400
So Principcal = $400
