The total cost is the sum of all the products that were purchased.
We have then:
For this case, the total cost is given by:
C = 3x + 4.50
Where,
x: represents the cost of each water.
Answer:
an expression in simplest form that represents the total amount of money you spent is:
C = 3x + 4.50
Number of cards of John: J
Number of cards of Alan: A
<span>John and Alan have a collection of x baseball cards:
J+A=x (1)
</span>John has x/4 cards:
J=x/4
<span>What fraction of the cards does Alan have?
</span>
Replacing J by x/4 in the equation (1)
(1) J+A=x
x/4+A=x
Solving for A:
x/4+A-x/4=x-x/4
A=4x/4-x/4
A=(4x-x)/4
A=3x/4
Answer: Alan has 3/4 of the cards
If you draw 2 yellow cards that would lead you to 0.16 but we are rounding it to the nearest hundredths so that would be 0.16 because you cant round up or down in the hundredths place.
hope that helps<span />
