Beth has $45 to spend on tulips, which are sold by the dozen. Suppose a dozen tulips costs $21.10. At most, how many dozens can Beth buy? Write a one-variable, one-step inequality to solve.
A)4
B)3
C)2
D)1
Let x be the number of dozens of tulips Beth can buy.
The inequality representing this situation is:
21.10x ≤ 45
To solve for x:
21.10x ≤ 45
x ≤ 45 / 21.10
x ≤ 2.13
Beth can buy at most 2 dozens of tulips.
Therefore, the answer is C) 2.
