Jane went to the mall and bough 2 pairs of jeans for j dollars each and 3 shirts for s dollars each. write an algebraic expression that shows how much jane spent at the mall.

2j+3s=Total Jane Spent

Step-by-step explanation:

-Jane went to the mall and bough 2 pairs of jeans for j dollars each.

So for jeans she payed 2 times j since each pair costs j dollars (2j)

-3 shirts for s dollars each.

So for shirts she payed 3 times s since each pair costs s dollars (3s)

-Now finally 2j+3s is our answer.

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:
