Algebra Final Exam Review

Mrs. Marietta goes to the grocery store and buys 4 oranges, 8 cans of corn, and 1 box of crackers. The oranges cost $1.78 each, the corn costs $2.42 per can, and the box of crackers costs $6.99. Write an equation that represents the total cost c of Jake's purchases.

• c = (4 + 1.78) + (8 + 2.42) + 6.99

• c = (4 + 1.78) · (8 + 2.42) + 6.99

• c = (4 · 1.78) + (8 · 2.42) + 6.99

• c = (4 · 1.78) · (8 · 2.42) · 6.99
