Answer:
1/5x - 12 = -7
Step-by-step explanation:
The first thing says 12 less THAN. Normally, when you see something in word problems like "less than" it means you need to switch the places.
So rather than 12 - 1/5, it's 1/5 - 12.
1/5 of a number means you are multiplying that number by 1/5. we'll use x (or any letter really, doesn't matter) to represent the unknown number.
Remember that if a variable and number is written together, it means multiplication.
So, 1/5x - 12 = -7.

I’m not completely sure though please let me know if I’m right!
If he needs $20, for a truck only has 10 and spends $2 already. He only has $8 left which means he needs a minimum of $12. So I'd say best guess. C or D.
