After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after <em>n</em> hours, an initial amount <em>A</em> of this substance decays according to
<em>A</em> / 2<em>ⁿ</em>
(x+1)^3+9

A contractor purchased 7 dozen pairs of work gloves for 103.32 dollars.
He incorrectly calculated the unit price at 14.76 per pair for his expense report.
Let’s correct his work.
Solutions.
=> 7 pairs for gloves for 103.32 dollars.
Let’s find the cost of each pair of gloves.
=> 103.32 / 7 = 14.76 dollars.
according to our solution, he has a correct answer. The only problem in his work is the Unit rate representation.
=> 14.76 dollars/pair
Answer: C
