Question

Latonya bought flowers for her mother. She spent $45. Each tulip was $1 and each rose was $2. She bought 3 more tulips than roses.

Let t be the number of tulips. Which algebraic sentence would help you figure out how many tulips Latonya bought?

A. t + 2(t + 3) = 45
B. t + 2(t – 3) = 45
C. 2t (t + 3) = 45
D. -3t + 2t = 45

Answer 1

Lets start from scratch.
45 is the number of money she spent that means that right side of = sign is 45
let m represents number of roses.
we can write:

t*$1+ m*$2 = $45

Since she bought 3 more tulips than roses that means that m = t - 3

when we express m we get:

t + 2*(t-3) = 45

the answer is B.
