# Create Equations (Unknowns in terms of the same variable)

Write and solve equations for the word problems:

1. You go to a burger joint.  A burger costs x.  Fries cost .45 less than burgers.  If you order 2 burgers and 3 orders of fries, and spend \$17.90, how much does a burger cost? How much do fries cost? 2. At a competing burger joint, drinks cost 50 cents less than fries. Burgers cost twice as much as fries. If you order 1 burger, one order of fries, and one drink, it costs \$7.70.  How much does a burger cost? How much do fries cost?  How much do drinks cost?
3. James and Richie took a math test.  Richie scored twice as many points as James did. Together, they got 117 points. How many points did Richie score?  How many points did James score?
4. James, Richie, and Naseeha all took the same science test.  James score 3 times as many points as Richie did. Nasheeha scored 4 more points than James did. All together, they scored 235 points. How many points did James get?  How many points did Richie get?  How many points did Naseeha get?
5. Bella and Mimi collect trading cards. Mimi has 5 fewer than 3 times as many cards as Bella does.  If Mimi has 47 cards, how many cards does Bella have?
6. Khizar and Umar are playing basketball.  Umar scores 6 more than 4 times as many points as Khizar does. Together they scored 76 points. How many points does Khizar score?  How many points does Umar score?
7. Anthony, Dylan, and Kevin are working on a group project together.  Anthony answers half as many questions as Kevin does. Kevin answers 8 fewer questions than Dylan does. If there are 38 questions on the project. How many did Anthony, Kevin, and Dylan each answer?
8. After they finished their project, Anthony, Dylan, and Kevin went out to get lunch. They each bought a sandwich.  Dylan's sandwich cost \$1 more than Kevin's sandwich. Anthony's sandwich cost 85 cents less than Kevin's sandwich. They each got a drink for \$2 each.  If they split the cost evenly, and each paid \\$7.05, how much did each boy's sandwich cost?
