Answer:

b

Step-by-step explanation:

His initial cost is $28,000. Every decade the value of the house doubles. We are in year 1975. Let's add 10 years (a decade) 1975+10= 1985. Since we added ten years, we will double $28,000 which is $56,000. Let's add 10 more years 1985+10 is 1995. Since we added 10 years more, we double $56,000 which is $112,000. Now we can still add 10 more years. Do the same thing you did for the first and second decades. You should get the year 2005 and $224,000. We can still add 10 more years to get to 2020. Our year will be 2015 and our total amount in dollar is $224,000² = $448,000. Since the value doubles every decade you ignore the 5.

Solnce55 [7]

Answer:100-7x

Step-by-step explanation:

If x people are coming, he will spend the following

Sandwiches =2.50 × x= 2.50x

Drinks = 1.50 × x= 1.50x

Gift bags =3 × x=3x

Money left

Sandwiches = 50-2.50x

Drinks =25-1.60x

Gift bags = 25-3x

Total money left = 50-2.50x+25-1.50x+25-3x

=50+25+25-2.50x-1.50x-3x

=100-7x
