1.A cell phone is advertised for 25% off the list price of D dollars. Write an algabraic expression that represents the sale price of the phone? 2. A car travels for 10 hours at an average speed of s miles per hour, write an algabraic expression that represents the total distance traveled by a car.

$0.75D ; 10s miles

Step-by-step explanation:

1)

Given that:

List price of phone = $D

Advertised price = 25% off the list price

Hence, sales price of phone :

(100% - 25%) × list price

Sales price = 75% × $D

Sales price = $0.75D

2)

Given that :

Time of travel = 10 hours

Speed of travel = s miles per hour

Total distance traveled = (speed of travel × time of travel)

Total distance traveled = (10 * s) miles
