At the beginning of the year, Savannah had $3o in savings and saved an additional $16 each week thereafter. Jacob started the year with $55 and saved $11 every week.
Let S represent the amount of money Savannah has saved t weeks after the
beginning of the year and let J represent the amount of money Jacob has saved t
weeks after the beginning of the year. Write an equation for each situation, in terms
oft, and determine the amount of money Savannah and Jacob have saved in the
week that they have the same amount of money saved.

9514 1404 393

Step-by-step explanation:

The y-intercept in the equation is the initial amount in savings. The slope is the amount saved per week.

  S = 30 +16t

  J = 55 +11t

__

These are equal when ...

  30 +16t = 55 +11t

  5t = 25 . . . . . . . . subtract 30+11t

  t = 5

  S = 30 +16·5 = 30 +80 = 110

After 5 weeks, both Savannah and Jacob will have saved $110.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
