Answer 1

(a) cost of a carton of egg = 50 Rs

cost of a loaf of bread = 25Rs

Delivery charge on every delivery = 30Rs

Total cost = 50+25+30= 105 Rs

(b) Cost of one loaf of bread = 25Rs

Cost of n carton of eggs = n × 50Rs

= 50n Rs

delivery charge= 30 rs

Total cost = 55+50nRs

(c) Cost of m loaves of bread= 25×m

= 25m Rs

Cost of n carton of eggs= 50×n

= 50n Rs

delivery charge= 30

Total cost = 30+ 50n + 25m Rupees
