Step-by-step explanation:
Given
A proportional relation is given between minutes spend in reading and no of pages
Suppose we choose the point , It shows that 2 minutes is taken to read three pages.
Similarly, for point , It shows four minutes is taken to read 6 pages.
In this way, 6 minutes is taken for 12 pages.
to solve for j first you need to cross multiply;
j × 35 = 42 × 55
35j = 2,310
j = 2,310 ÷ 35 (did the inverse operation)
j = 66
Hope that helps :D
