Jenna is opening a clothing store. she plans to start by selling t-shirts. if it costs her $7 for each shirt, $2 for ink per shirt, and $0.10 a bag, what is her unit cost per shirt?

$9.10

Step-by-step explanation:

Just add up all your numbers $7 + $2 + $0.10 = $9.10

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:
