Question

Erica has some stickers in her sticker album. Each week she plans to add 9 stickers. Erica had 50 stickers after 4 weeks. Assume the relationship is linear. Find the rate of change and initial value.

Answer 1

Rate of change: 9
Initial value: 14

Step-by-step explanation:
9 x 4 = 36 (she adds 9 stickers every week, it's 4 weeks)
50 - 36 = 14 (subtract what she added to find initial value)
