an adult has 4.94 x 10^13 cells = 49,400,000,000,000
49,400,000,000,000 - 26,000,000,000 = 49,374,000,000,000
scientific notation form : 4.9374 x 10^13
Answer:
Discount = $30, Final price = $90
Step-by-step explanation:
25% is one quarter. 120/4=30
One quarter of 120 is 30, so - 30 would give discounted price of $90.
Similarly you could think of it like the discounted price is 75% of the original one and do 120x0.75=90 to find 75% of 120.
Hope this helped!
