Answer :
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
