5a = b + 1
Example
A. Five plus a equals b squared plus one.
B. Five times a equals twice b plus one.
Write a problem based on the given information.
C. Five times a equals b squared plus one.
D. The quotient of f ve and a equals b squared plus
f = cost of fries f + 1.50 = cost of burger one.

4(f + 1.50) – f = 8.25

The cost of fries + $1.50 = cost of burger
Answer
4(The cost of a burger) – cost of fries = 8.25

The cost of a burger is $1.50 Write a Problem
more than the cost of fries. Four
Answer times the cost of a burger minus Write a problem based on the given information.
the cost of fries equals $8.25. h = Tiana’s height in inches
How much do fries cost? h – 3 = Consuelo’s height in inches
3h(h – 3) = 8262

A. Consuelo is 3 inches shorter than Tiana.
Your Turn! The product of Consuelo’s height and three times
Tiana’s is 8262. How tall is Tiana?

Write a Formula B. Consuelo is 3 inches taller than Tiana.
Translate the sentence into a formula. The area of The product of Consuelo’s height and three
a circle equals the product of π and the square of times Tiana’s is 8262. How tall is Tiana?
the radius r.
C. Consuelo is 3 inches shorter than Tiana.
A. A = π + r2 The sum of Consuelo’s height and three times
B. A = πr² Tiana’s is 8262. How tall is Tiana?
C. A = 2πr D. Tiana is 3 inches shorter than Tiana.
D. A = 2r + π
The product of Consuelo’s height and three
times Tiana’s is 8262. How tall is Tiana?
