Forming Equations from Word Problems

To form an equation from a word problem, we can recognize variables and operations from keywords.

Solving the Question

Let the number of weeks be a.

We're given:

• Goal amount is $200 at minimum
• Money earned is $15a
• Current amount is $32

Because $200 is the minimum account required, we know that the amount earned must be greater than or equal to 200.

`200\leq`

Our current savings and money can be calculated by adding 15a and 32:

`200\leq15a+32`

Answer

`200\leq15a+32`
