Question

If Davis buys 10 notebooks, then he will have $10 left over. If he tries to buy 15 notebooks, then he will be $10 short. How much money does Davis have? ASAP

Answer 1

$ 50

Explanation:

c =cuadernos

x= dinero davis

10c+10=x

15c- 10=x

10c+10=15c- 10

20=5c

c=4

=>10(4)+10=x

x=50

15(4)- 10=x

x==50
