Question

Tamara bought yarn for $39 and 2 pairs of knitting needles. Her total cost for the yarn and knitting needles was $69. Tamara writes an equation that represents the cost of each pair of knitting needles. If k represents the cost of each pair of knitting needles, which statements about verifying the value of k are true? Check all that apply.

Answer 1

If you see the below statements among the choices, then you can select these as the answers:
a.) 39 + 2k = 69
             2k = 69 - 39
          2k/2 = 30/2
               k = 15

b.) 39 + 2k = 69
 39 + 2(15) = 69
     39 + 30 = 69
             69 = 69
