Arlene set up tables for a dinner. She put 10 chairs at each table. If t represents the number of tables Arlene set up, which equation could be used to find c, the number of chairs Arlene used? Group of answer choices

c = 10t

t = 10c

t = c + 10

c = t + 10

c = 10t  (first answer choice)

Explanation:

Let's say we had 1 table. This would mean we have 10 chairs.

Now let's say we had 2 tables. So we now have 2*10 = 20 chairs.

If we had 3 tables, then we have 3*10 = 30 chairs. And so on.

The rule is:

number of chairs = 10*(number of tables)

We can shorten that down to

c = 10*t

c is the number of chairs and t is the number of tables. The letters are placeholders for positive whole numbers. You can think of them as boxes where a number will go inside.

47 - 90 = 43

43 - 180 = x

x = 137
