Question

The members of a knitting club are buying supplies for their next meeting. For the club, they need to buy a new patterns book for $3.50. For each member, they need to buy a set of knitting needles for $3.20 and a ball of yarn for $5.40. They spent $63.70 in total. Write and solve an equation to determine how many members the knitting club has

Answer 1

The knitting club has 7 members

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

The knitting club has 7 members
