Question

I’m Carrie saved money to spend while on a one-month vacation to Europe. On day 8, she had $2,400 remaining. On day 16, she had $1,600 remaining. If her spending is modeled by a linear function, how much money did she initially take with her to Europe?

Answer 1

3,200

Explanation:

slope =

1,600 - 2,400

16 - 8

= -100

y = mx + b

2,400 = -100(8) + b

b = 3,200

thus,

y = mx + b

y = -100x + 3,200

y = -100(0) + 3,200

y = 3,200

Answer 2

$3200, hope it helps!
