Nick paid $2.94 in sales tax on an item that cost $42.00 before tax. at that rate, how much would he pay in sales tax for an item that cost $58.00 before tax

2.94 / 42 = 0.07

0.07 x 100 = 7% tax

58 x 1.07 = 62.06

62.06 - 58 = 4.06 Dollar tax

the answer

b. they are parallel and will never intersect.

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
