x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

$y=0.45x+40$

For y=48.10

substitute

$48.10=0.45x+40$

Multiply by 100 both sides

$4,810=45x+4,000$ ----> equation without decimals

solve for x

$45x=4,810-4,000\\45x=810\\x=18\ min$

To find out the total minutes we need to sum

$18\ min+700\ min=718\ min$
