The total surface area is 121.8yd^2 and the lateral surface area is 79.8yd^2.
121.8 - 79.8 = 42
Answer:
it would be c when fully simplified.

In the student's equation, there are many problems. Nickels are worth 5 cents, represented by .05, not 50 dollars. Also, the coeffient 5 should not be placed there, it belongs with 5(.1), as we already know how many dimes there are. If we were able to make a new one, it would be, 5(.1)+.05n=1.20.
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.
