Unit 1 Review Algebra 2

Linda received a phone bill that shows a monthly fee of $19.99 plus 0.05 cents charge per minute of time used.

Write a function that can be used to determine Linda’s monthly cost of phone bill, B using her minutes, m.

• $B(m)=19.99m+0.05$
  

• $m(B)=19.99B+0.05$
  

• $B(m)=0.05m+19.99$
  

• $m(L)=0.05m+19.99$

Linda received a phone bill that shows a monthly fee of $19.99 plus 0.05 cents charge per minute of time used.

Write a function that can be used to determine Linda’s phone usage, in minutes based upon her phone bill.

•  $m\left(B\right)=\frac{B-19.99}{0.05}$ 
  

•  $m(B)=19.99m+0.05$ 
  

•  $B\left(m\right)=0.05m+19.99$ 
  

•  $m\left(B\right)=\frac{0.05+B}{19.99}$ 
  

•  $B\left(m\right)=19.99m+0.05$

Jordan’s pool contains 4900 gallons of water. It is being completely cleaned and draining at a rate of 250 gallons per hour.

Write a function that can be used to determine the remaining gallons of water in Jordan's pool, G, using the hours it takes to drain, h.

•  $G(h)=4900\ +\ 250h$ 
  

•  $G\left(h\right)=4900\ -\ 250h$ 
  

•  $h\left(G\right)=4900-250h$ 
  

•  $G\left(h\right)=4900h-250$ 
  

•  $h\left(G\right)=4900+250h$

Jordan’s pool contains 4900 gallons of water. It is being completely cleaned and draining at a rate of 250 gallons per hour.

Write a function that can be used to determine the hours it takes to drain, h, using the gallons of water in the pool, G.

•  $G(h)=4900\ +\ 250h$ 
  

•  $h\left(G\right)=\frac{G-250}{4900}$ 
  

•  $h\left(G\right)=\frac{G-4900}{-250}$ 
  

•  $G\left(h\right)=4900h-250$ 
  

•  $h\left(G\right)=\frac{h-4900}{-250}$
