Kevin used a $50 bill to pay for 4 shirts. The cashier gave him $6.44 in change.
Each shirt cost the same amount. What
was the cost of each shirt?

Each shirt would cost 10.89$

Step-by-step explanation:

By subtracting 6.44 from the total (50), we get 43.56. Divide that by 4 and you get the answer, 10.89$

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

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
