A grocery store in town marks up the price of fresh strawberries in the winter by 15%. A drought causes an additional increase of $2.50 for each carton of strawberries. Let s represent the cost of one carton of strawberries. Write a function M(s) to represent the price of strawberries after the 15% markup.

1.15s + $2.50

Step-by-step explanation:

Given that:

Markup percentage of strawberries in winter = 15%

Additional increase due to drought = $2.50

Cost of a carton of strawberry = s

Cost of strawberry after Markup ; M(s)

M(s) = (original cost * ( 100% + markup %)) + additional cost due to drought

M(s) = (s * (100% + 15%)) + $2.50

M(s) = 115% * s + $2.50

M(s) = 1.15s + $2.50

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

Distance a body falls from rest varies directly as the squares of the time it falls

Let distance = s    

      time = t

Therefore , s = k

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k

64 = k

 k  =

 k = 16 ft/

We have to find how much he will fall in 10 seconds.

s = k

s =

s =

s = 1600 ft
