Question

if 160. frankies were sold, how many more sandwiches should be sold in order to have nither a profit nor a loss​

Answer 1

$\huge \red{ANSWER}$

He sold 75 sandwiches which means he has inherited a profit of Rs. 375 (75x5)

He sold 160 Frankie's which means he has inherited a loss of Rs. 480 (160x3)

total profit= Rs. 375

total loss= Rs. 480

loss is of Rs. 105

to overcome the loss he has to sell 21 sandwiches

105/5= 21

amount to overcome total loss/ profit per sandwich
