Answer:

B) 200 + 4c - 6b

Step-by-step explanation:

Be,

c = number of cards sold at $4

b = number of cards purchased at $6

x = money at the beginning of the day = $200

y = money at the end of the day

The variables x and c owe positive values because they represent possession or income of money, while b must be negative because purchases are expenses.

Then, the following equation is formed:

y = x + 4c - 6b

Substituting x for its value, you get

y = 200 + 4c - 6b

Hope this helps!

Michael has $10 to put in a savings account . He has two options for a saving account : Option 1 will add $ 100 to his account e
nekit [7.7K]

Answer:

Option 1:

He starts with $10, and for each week, we add $100

Then his balance as a function of weeks will be:

f(w) = $10 + $100*w

option 2.

Again, we start with $10, and for each week that passes this is doubled, then the equation will be:

g(w) = $10*(2)^w

Now, we want in week w = 7 to have at least $700, then we need to replace w by 7 in both equations and see which one is better.

option 1:

f(7) = $10 + $100*7 = $710

With option 1 he will have enough

option 2:

g(7) = $10*(2)^7 = $1280

Again, he will have more than $700 in week 7, and we can clearly see that this option is better.
