The office manager of an electron campaign office needs to print 5000 postcards. Supose that it cost 2 cents to print one large postcard and 1 cent to print a small one. If $88 is allocated for printing postcards, how many of each can be printed? If x is the number of large postcards what will be a good equation to decribe the situation?

The office manager of an electron campaign office needs to print 5000 postcards. It costs 2 cents to print one large postcard and 1 cent to print a small one. $88 is allocated for printing postcards. As the total number of postcards that need to be printed is 500, if the number of large postcards printed is x, the number of small postcards printed is 5000 - x

2*x + 5000 - x = 8800

=> x = 3800

The number of large postcards that can be printed is 3800 and the number of small postcards that can be printed is 1200.

`0.02x+0.01(5000-x)=88`

`2/100 x +1/100(5000-x)=88`

`2x-5000- x=8800`

`x-5000=8800```

`x=3800`  (large size postcard)

`5000-3800=1200`   (small size postcards)
