Question

1. becky wants to buy some fish for her aquarium. she has $20 to spend and the fish cost $2.50 each. determine how many fish becky can afford. then interpret the solution. (example 1)

Explanation:

Step1: Define variables and equation

Let $n$ = number of fish. Total cost: $2.50n \leq 20$

Step2: Solve for $n$

$n \leq \frac{20}{2.50}$
$n \leq 8$

Step3: Interpret the solution

Since fish are whole units, $n$ must be a non-negative integer. The maximum whole number satisfying the inequality is 8.

Answer:

Becky can afford 8 fish. This means that purchasing 8 fish will cost her exactly $\$20$ (since $8 \times 2.50 = 20$), which uses up all her available money, and she cannot buy a 9th fish as it would exceed her $\$20$ budget.
