Modeling with Equations You have $60 and your sister has $120. You are saving
$14 per week and your sister is saving $10 per week. How
long will it be before you and your sister have the same
amount of money? What amount would you have the same?
You must include the equation and the intermediate
steps used to arrive at the answer

Step-by-step explanation:

you

60 +14*number of weeks

sister

120+10*number of weeks

let x be the number of weeks until they have the same amount of money

60+14x = 120+10x ; isolate like terms

14x -10x = 120-60

4x = 60; divide both sides by 4

x= 15 weeks

120+10*15 = 120+ 150 = $270 will be the amount they will have the same

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
