Answer:
17%, or $25.50
Step-by-step explanation:
If Ricardo has already saved 83% of the money, then he needs to save 17% more, because 83% + 17% = 100%
So what you need to do to figure out the answer is to find out 17% of $150
You first have to convert 17% into decimal form which is 0.17.
Then, you multiply 0.17 × 150 = 25.5
Ricardo needs $25.50 to buy the skateboard.
Hope this helped.
