Question

Lalo has 1,500 minutes per month on his cell phone plan. How many more minutes can he use if he has already talked for 785 minutes? What is the solution,

Answer 1

Answer:

715 minutes

Step-by-step explanation:

we know that

To find out how many more minutes he can use, subtract the number of minutes he has already talked from the number of minutes  of his plan

Let

x -----> the number of minutes  of his plan

y -----> he number of minutes he has already talked

so

$x-y$

we have

$x=1,500\ min\\y=785\ min$

substitute

$1,500-785=715\ min$
