You're a plumber, and you'll charge a certain amount just for showing up at a job, and you'll also charge a certain rate per hour of work (billed in half-hour increments). Materials are a separate charge not
considered in this problem.
If you charge $326 to show up at a job and work three hours, and you charge $548.50 to show up at a job
and work five and a half hours, then what is your charge just to show up at a job? What is your per-hour
• charge? Write a linear function that expresses the amount you bill to show up and perform a job as a
function of the number of hours worked. How much will you charge to show up at a job and work for four
hours?

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

answer is 144

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

b, i believe, but not sure.
