After value putting, if the number of guests represented by the variable (g) is 17 then the cost pf the food is $220.
In the given question we have to evaluate the expression if the number of guests represented by the variable (g) is 17.
An expression to represent the cost of the food for a catered lunch is 50+10g.
The fee for the catering is $50 and then there is a $10 charge for each lunch box.
Since g is representing the number of guests.
The the value of g is given 17.
Now putting the value of g in the given expression.
=50+10g
=50+10*17
=50+170
=220
Hence, if the number of guests represented by the variable (g) is 17 then the cost pf the food is $220.
