1.Mark makes Php 40.00 per hour if he works 40 hours or less.If works overtime,he makes an additional Php 5.00 per hour as overtime pay.What would be his total pay if he worked 58 hours?

2.The world's greatest known ocean depth of 36,201 feet was recorded in the Marianas Trench.The altitude of the Mt.Everest,yhe highest point on earth,is 29,028 ft.How many ft above the bottom of the Marianas Trench is a climber who has reached the top og Mt.Everest.

3.The DLC Company reported the following four quarterly earnings : Php 600,500 ,Php 6,480 Php 230,456 and Php 8500.What was the total profit or loss for the year

1. $40(40) + $45(18) = ?

2. 36,201 + 29,028 = ?

3. I don't know what "Php" means nor the costs of operating.

Php is pesos..

Wat is the formula?
Thanks

1. To calculate Mark's total pay, we need to consider his regular pay for the first 40 hours and his overtime pay for the remaining hours.

Regular pay for 40 hours = Php 40.00/hour × 40 hours = Php 1,600
Overtime pay for 18 hours = Php 5.00/hour × 18 hours = Php 90

Total pay = Regular pay + Overtime pay = Php 1,600 + Php 90 = Php 1,690

Therefore, if Mark worked 58 hours, his total pay would be Php 1,690.

2. To calculate how many feet above the bottom of the Marianas Trench the climber is when reaching the top of Mt. Everest, we need to subtract the depth of the trench from the altitude of Mt. Everest.

Height above the bottom of the Marianas Trench = Altitude of Mt. Everest - Depth of Marianas Trench
= 29,028 ft - 36,201 ft
= -7,173 ft (negative value because the climber is below sea level)

Therefore, when the climber reaches the top of Mt. Everest, they are 7,173 feet below the bottom of the Marianas Trench.

3. To calculate the total profit or loss for the year, we need to add up the quarterly earnings.

Total profit or loss = Php 600,500 + Php 6,480 + Php 230,456 + Php 8,500
= Php 846,936

Therefore, the total profit or loss for the year is Php 846,936.
