x-------> amount that Evans uncle gave for the birthday
Part a) What portion of money will he spend on comic books?
we know that
1) Evan puts half of the money in his savings account
so
the rest is equal to
2) Evan spend of the money on bubble gum to share with his friends
the rest is equal to
3) Evan buy comics with the rest
the rest is equal to
therefore
the answer Part a) is
The portion of money that Evan will spend on comic books is
Part b) Evans uses some of his comic book money to buy a magazine for $4. Evans uncle gave him $30, what fraction of the money did he spend on he magazine
The portion of money that Evan will spend on comic books is
So
$
by using proportion
therefore
If the question refers to the fraction with respect to the money used for the comics
then
the answer Part b1) is
If the question refers to the fraction with respect to the total money
then
by using proportion
the answer Part b2) is
Answer: 24 and 37
Step-by-step explanation:
Let the numbers be x and y . Also let us pick x as the larger number.
From the first statement :
x + y = 61 ............................ equation 1
From the second statement :
x = y + 13 ............................equation 2
Solving the resulting linear equations by substitution method, substitute x = y + 13 into equation 1, then
x + y = 61 becomes
y + 13 + y = 61
2y + 13 = 61
2y = 48
y = 24
Substitute y = 24 into equation 2 , then
x = y + 3 becomes
x = 24 + 13
x = 37
Therefore the numbers are 24 and 37
