Answer:
s ≤ 60 - (3 ÷ 1/15)
Step-by-step explanation:
Minimum of blankets to crochet = 3
She has 60 days to crochet
She crochet at a rate of 1/15 of a blanket per day
Therefore to crochet 1 blanket
Number of days needed =x
1 blanket = rate per day * x days
1 = 1/15 * x
1 = 1/15x
Divide both sides by 1/15
x = 1 ÷ 1/15
= 1 × 15/1
= 1×15
x = 15
15 days needed to crochet 1 blanket
To crochet 3 blanket = 15 days × 3 blanket
=45 days needed.
Darcie can skip = 60 days - 45 days
= 15 days
The inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
s ≤ 60 - (3 ÷ 1/15)
Solving the inequality
s ≤ 60 - (3 ÷ 1/15)
s ≤ 60 - (3×15/1)
s ≤ 60 - 45
s ≤ 15
The y-intercept is (0,-36), the x-intercepts are (2,0), (3,0), and (6,0), and it is a cubic function.
A false hypothesis helps to understand what factors are not related to a certain outcome. This helps center experiments around hypotheses that are more relevant.
