Answer:
(a) They paid $25-$15=$<<25-15=10>>10 to make each wreath.
(b) They collected $15114=$<<15114=1710>>1710.
(c) They made $1710-$10114=$<<1710-10114=180>>180.
(d) They sold $180/$15=<<180/15=12>>12 wreaths.
Explanation:
Sure, here is a breakdown of the solution:
(a) The cross-country team paid $10 to make each wreath because they sold the wreaths for $25 and made $15 for each wreath they sold, so the cost to make each wreath was $25-$15=$10.
(b) They collected $1710 because they sold 114 wreaths and made $15 for each wreath they sold, so they collected a total of $15*114=$1710.
(c) They made $180 because they collected $1710 and it cost them $10 to make each wreath, and they sold 114 wreaths, so the total cost of making all the wreaths was $10*114=$1140. They made $180 because they collected $1710 and it cost them $1140 to make all the wreaths, so their profit was $1710-$1140=$180.
(d) They sold 12 wreaths because they made $180 and it cost them $15 to make each wreath, so they sold $180/$15=12 wreaths.
