Valentino starts with a population of 1,500 amoebas that increases 35% in size every hour for a number of hours, h. the expression 1,500(1+0.35)h finds the number of amoebas after h hours. which statement about this expression is true? a. it is the initial population raised to the growth factor after h hours. b. it is the sum of the initial population and the percent increase. c. it is the sum of the initial population and the growth factor after h hours. d. it is the product of the initial population and the growth factor after h hours.

 It is the product of the initial population and the growth factor after h hours.

Step-by-step explanation:

Given: Valentino starts with a population of 1,500 amoebas that increases 35% in size every hour for a number of hours, h.

The expression finds the number of amoebas after h hours.

On simplifying the above expression we get, .

At h=0, the initial population of amoebas = 1,500

At h=1, the population of amoebas =

The growth factor =

Hence, the expression , is the product of the initial population and the growth factor after h hours.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
