The total cost of calculator and a bag is 845. The bag cost 257 less than the calculator. How much does the calculator?

Answer 1

Answer:

551

Step-by-step explanation:

given calculator and bag is 845

calculator+bag= 845

calculator= 845-bag .....eq1

given calculator is 257 less than bag

bag= calculator-257

calculator= bag +257 ......eq2

from 1 and 2

bag+257= 845-bag

2 bag = 845-257

2 bag= 588

bag = 294

substitute bag = 294 in eq2

calculator = 294+257 = 551
