Ok.
1 lb of spinach sells for $3.50.

xxstudyingstuffxx · Answer

Well, if you have learned ratios then you know that there is 1 pound of spinach for every 3.5 dollars. The total amount of dollars would be however many pounds of spinach was bought times the amount of money per pound.

mathstudent55 · Answer

You can use the price of the spinach to figure out how much 2 lb, or 3 lb, or other amounts would cost.

xxstudyingstuffxx · Answer

Does that make sense?

anonymous · Answer

no

mathstudent55 · Answer

1 lb of spinach costs $3.50

2 lbs is 2 * 1 lb, so let's multiply both the amount and the price by 2 to see how much 2 lb would cost.

1 lb costs $3.50
2 * 1 lb = 2 lb costs $3.50 * 2 = $7.00

2 lb of spinach costs $7.00

Ok so far?

anonymous · Answer

yes

anonymous · Answer

im thinking the answer is c

mathstudent55 · Answer

Now let's try 3 lb.
Similar to what we did before, 3 lb = 3 * 1 lb.

1 lb costs $3.50
3 * 1 lb = 3 lb costs $3.50 * 3 = $10.50

3 lb costs $10.50

xxstudyingstuffxx · Answer

y = total amount of money. x = amount of spinach bought. The amount of spinach bought determines how much money is spent. y(the amount of money) = 3.50 * x(the amount of spinach bought.

anonymous · Answer

soooo b

xxstudyingstuffxx · Answer

I didn't get one, but I gave mathstudent55 one.

mathstudent55 · Answer

Now instead of trying to find the price of a specific number of pounds, we use the letter x, called a variable in math, to represent any number we want.

1 lb of spinach costs $3.50

How much do x ponds of spinach cost?

x = x * 1, so 

x * 1 lb = x lb of spinach costs $3.50 * x

We can simplify the writing and write:

x pounds of spinach cost 3.50x

xxstudyingstuffxx · Answer

And yes, you are correct.

xxstudyingstuffxx · Answer

Can I get a metal?

mathstudent55 · Answer

Your problem states that x is the number of pounds, and y is the cost.

Since x pounds of spinach cost 3.50x, and the cost is y, we get

y = 3.50x

@hackerlife120 Same concept as the last question. C, or the amount of money total, is equal to $10.98 times the amount of pounds the customer bought. So, what would the answer be?
