Anew road was added near riana's neighborhood. the road is 5 miles long and the city plans to place a street light every 1/10 mile. there already is a streetlight at the beginning of the new road. how many streetlights will be placed on the new road

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 final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
