Jaden has a part-time job working for a landscaping company. He earns $25 for each lawn-mowing job, l , and $20 for each pulling-weeds job, w . This can be modeled by 25l+20w . Evaluate for l=4 and w=6 to find how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs
To find out how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, we can substitute the given values into the expression 25l + 20w:
25(4) + 20(6)
= 100 + 120
= <<220=220>>220
Therefore, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.
The formula for finding the surface area of a cube is 6s2 , where s is the length of each side of the square. Evaluate for s=10 to find the number of square centimeters ( cm2 ) for the surface area of a cube with a side length of 10 cm
To find the surface area of a cube with a side length of 10 cm, we substitute the given value into the formula 6s^2:
6(10)^2
= 6(100)
= <<6*100=600>>600
Therefore, the surface area of a cube with a side length of 10 cm is 600 cm^2.
Alicia works for Thomas Edison Electrical Company. She earns $100 for going to a customer’s house and $65 per hour, h , for the job. This is modeled by 65h+100 . Evaluate for h=3 to find how much Alicia will earn for a job that takes 3 hours.
To find out how much Alicia will earn for a job that takes 3 hours, we substitute the given value into the expression 65h + 100:
65(3) + 100
= 195 + 100
= <<195+100=295>>295
Therefore, Alicia will earn $295 for a job that takes 3 hours.
