Answer:

I. Direction: Solve each problem. Write your answers on a sheet of paper.

1. Write an algebraic equation for the cost of 21 liters of gasoline, if x pesos

per liter is P2,092.

x= (2, 092)(21L), where x is the total cost of the gasoline

2. Samantha is y years old now. Write an algebraic equation for Samantha's

age if her age 5 years from now is 17.

y+5=17, where y is Samantha's age now

3. Leo is g centimeter tall. Ralph's height is 4 less than thrice the height of

Leo. Write an algebraic equation showing the difference of Leo's height

when subtracted from Ralph's height will result to 240 centimeters.

(3g-4)-g=240 cm

4. In three years, the price of a new model of an S6-mobile phone will be six

more than twice its current price. If the projected price of the new S6 phone
