The answer is: $40
What we know:
• Emily bought a toaster for $36.
• The toaster was was on sale for 10%.
Step-by-step explanation:
If Emily get's a 10% discount on the toaster, then 100% subtracted from 10% would give you 90% If you where too slove this, you would have 0.90o=36. (O stands for the original price!) Which means the answer is 40$
If the original price is $40, and since Emily had a 10% discount. That being said, the discount amount would be 4$. If you where too subtract 4$ from 40$ you'll end up with 36$, which is the amount she paid for the toaster.
That being said, 40$ is the correct answer!
