Sam has $2,450 in his bank account. he spends $20 each week on gas money. after how many weeks will sams account balance fall below $1000 in inequality form?

Step-by-step explanation:

The balance (b) in Sam's account will be the initial balance less 20 times the number of weeks (w) that he withdraws gas money.

  b = 2450 -20w

We want the inequality to express the condition that this balance is below 1000:

  b < 1000

  2450 -20w < 1000 . . . . . substitute for b

__

The solution to this can be found by subtracting 2450, then dividing by -20.

  -20w < -1450

  w > 72.5

If weeks are counted in whole numbers, Sam's balance will be below $1000 after 73 weeks.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
