Answer:

The result is 8.75 x10^8

Step-by-step explanation:

When you multiply numbers in scientific notation, you do the following:  

Multiply the base numbers normally:  

2.5* 3.5 = 8.75  

The exponents with base 10 are added and the base stays the same in the result:  

10^10x10^-2= 10^(10+(-2))=10^8.  

The answer is the multiplicaton of both 8.75*10^8.

seraphim [82]
Well we want to find out how much more will it cost to rent a ski boat than a sailboat for four hours. 

All we have to do is Multiply 73 by 4 for the sailboat which gives you $292 

Now we do the same for the ski boat. $88 * 4 = $352 

So we now have to find out how much more it will cost for a ski boat than a sail boat. All we do is subtract 352 by 292
