Step-by-step explanation:
Mrs.Rose received a 35% discount on her cell phone. The price of her cell phone came out to be $180. How much was the original price of her cell phone? <the answer is -145 :) >
Answer:
243 dollars
If she got 35% discount, and the price ended up being 180, we do the following:
180*.35=63
180+63=243 dollars.
time after 40 meters to 80 meters=12-7=5 s
distance=80-40=40 m
max. speed=40/5=8 m/s
