Answer 1

AnswEr :

Given Relation,

$\tt Cost = (Rs. 4.70 \times No.of \ Children )+ Rs.86$

Case I :

A total number of 13 children went to the party

Then,

$\colon \implies \tt Cost = (4.70)(13) + 86 \\ \\ \colon \implies \tt Cost = 61.1 + 86 \\ \\ \large{\colon \implies \boxed{\boxed{\tt Cost = Rs 147.1}}}$

Case II :

Total cost of hiring the bouncy castle is 165.90

Let the number of children who attended the party be x

Now,

$\leadsto \tt 165.90 = 4.70x + 86 \\ \\ \leadsto \tt 4.70x = 79.9 \\ \\ \large{\leadsto \boxed{\boxed{\tt x = 17}}}$

A total number of 17 children went to the party
