5/12+5/12=10/12
10/12+10/12=20/12 wich =1.666666666666667theres ur answer to one.

Sec is also known as 1/cos.
Use the calculator to find 1/cos19
Each football is sold for $9.95. To make one of these football costs $7.10.
There is a profit of $2.85. Divide 11,400 by 2.85 to see how many footballs would have to sell to break even.
11,400 / 2.85 = 4000.
4000 footballs would have to be sold to break even.
A=p(1+i/m)^mn
A=26,000÷(1+0.06÷2)^(2×7)
A=17,189.06
