A guitar costs $545.95. If tax is 9.5%, what will the total price of the guitar be?

The total price of the guitar will be $597.82

Step-by-step explanation:

Multiply 545.95 by 0.095 and you get 51.87. Add 51.87 to 545.95 and you get 597.82

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
