The cost of 45 packets of instant noodles given the direct variation is $52.335

Direct variation

let

  • Amount spent on noodles = n
  • Number of Packets purchased = p

n = k × p

  • Where,

k = constant of proportionality

34.88 = k × 30

34.88 = 30k

k = 34.88/30

k = 1.16266666666666

Approximately,

k = 1.163

Find n when p = 45

n = k × p

= 1.163 × 45

n = $52.335
