A small business takes out loans from three different banks to buy some new equipment. The total amount of the three loans is $19,000. The first bank offered an interest rate of 16%. The second bank offered a rate of 18% and the amount borrowed from
this bank was $5000 less than twice as much as the amount borrowed from the first bank. The third bank offered a rate of 15%.
The total annual interest was $3050. How much did they borrow from the third bank?

Given that an artist uses 8 orange beads, 3 red beads, 4 green beads and 1 string for making a special tricolored bracelet.

Given that there are 15 orange beads, 86 red beads, 92 green beads, and 17 pieces of string, the number of special tricolored bracelets that can be made is 1.

This is because, since 8 orange beads is needed for the special tricolored bracelets and there are only 15 orange beads the available, there will only be 7 orange beads left for the second tricolored bracelet.
