sweet [91]

Answer:

$\large \boxed{\text{4.25 lb}}$

Step-by-step explanation:

$\text{Cost of onions} = \text{3 lb} \times \dfrac{\text{0.98 }}{\text{1 lb}} = \text{2.94}$

Remaining money = Money available - Cost of onions = 21.45 - 2.94 = 18.48

I lb of cherries costs 4.35 , so

$\text{Pounds of cherries } = 18.48 \times \dfrac{\text{1 lb cherries}}{\text{4.35}} = \text{4.25 lb of cherries}\\\\\text{Lacey can afford to buy $\large \boxed{\textbf{4.25 lb}}$ of cherries.}$
