The oakville high school marching band band sold gift wrap to earn money for a band trip. Solid color gift wrap sells for $3.50 per roll. The band needs to earn $2500 for an upcoming competition. If the bad Sells 325 rolls of printed paper, write and solve a linear equation to find the number of solid paper they must sell

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
