Susan and Jan sold T-shirts for a fundraiser. Together they sold 85.
Jan sold 5 less than twice the amount of Susan. Write an equation to
model the situation so that we can find how many shirts each girl sold.
10. Linda was selling tickets for the school play. She sold 10 more adult
tickets than children tickets and she sold twice as many senior tickets as
children tickets. Adult tickets cost $5, senior tickets cost $3 and children
tickets cost $2. Linda made $700. Write an equation to model the situation
so that we can find the amount of tickets sold to adults, children, and seniors.
Create a 1 variable inequality to model a real world problem.
11. Ellen is having a dinner party. She is trying to decide whether to hire a
caterer or make the food herself. The caterer charges $150 in addition to
$15 per person. If she makes the food herself it will cost her $25 per
person in groceries. Write an inequality to model the situation so that we
can find how many people Ellen can invite so that making the food herself
is cheaper than hiring a caterer.
12. Members of the band boosters are planning to sell programs at football
games. The cost to print the programs is $150 plus $0.50 per program.
They plan to sell each program for $2. Write an inequality to model the
situation so that we can find how many programs must be sold to make a
profit of at least $500.
I really need help Please

J = 2S - 5
J + S = 85
(2S-5) + S = 85
Solve for S, then J.
