x=+-k
k=+-x
B. Because if you simplify the numbers they all become 2/3.
Answer:
<u>The knitting club has 7 members </u>
Step-by-step explanation:
1. Let's check the information provided to us to answer the question correctly:
Cost of new patterns book = US$ 3.50
Cost of set of knitting needles for each member = US$ 3.20
Cost of set of a ball of yarn for each member = US$ 3.20
2. Write and solve an equation to determine how many members the knitting club has.
Number of members of the knitting club = x
For solving for x, we can use this equation:
3.50 + 3.20x + 5.40x = 63.70
8.60x = 63.70 - 3.50
8.60x = 60.20
x = 60.20/8.60
x = 7
