Zendaya has $540 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.

She buys a new bicycle for $269.88.
She buys 4 bicycle reflectors for $10.57 each and a pair of bike gloves for $17.76.
She plans to spend some or all of the money she has left to buy new biking outfits for $65.65 each.

To determine the number of biking outfits \( x \) that Zendaya can purchase while staying within her budget, we first need to calculate her total expenses after buying the bicycle, reflectors, and bike gloves.

  1. Cost of the bicycle: $269.88
  2. Cost of 4 bicycle reflectors: \( 4 \times 10.57 = 42.28 \)
  3. Cost of bike gloves: $17.76

Now we can calculate the total expenses:

\[ \text{Total expenses} = \text{Cost of bicycle} + \text{Cost of reflectors} + \text{Cost of gloves} \]

\[ \text{Total expenses} = 269.88 + 42.28 + 17.76 \]

Calculating this:

\[ \text{Total expenses} = 269.88 + 42.28 = 312.16 \] \[ \text{Total expenses} = 312.16 + 17.76 = 329.92 \]

Next, we find how much money Zendaya has left after these purchases:

\[ \text{Money left} = 540 - 329.92 = 210.08 \]

Now, she plans to buy outfits that cost $65.65 each. The amount spent on \( x \) outfits is \( 65.65x \).

To stay within her budget, the money she spends on outfits must be less than or equal to the money left:

\[ 65.65x \leq 210.08 \]

Now, we can solve for \( x \):

To isolate \( x \), divide both sides by 65.65:

\[ x \leq \frac{210.08}{65.65} \]

Calculating the division:

\[ x \leq 3.2 \]

Since \( x \) represents the number of outfits, it must be a whole number. Therefore, the maximum number of outfits Zendaya can purchase is 3.

Inequality:

\[ x \leq 3 \]

ok now write the inequality in one line

The inequality in one line is:

\[ 65.65x \leq 210.08 \]

what does /leq mean?

The symbol \(\leq\) means "less than or equal to." It is used in mathematical inequalities to indicate that the value on the left side is either less than or exactly equal to the value on the right side.

For example, in the inequality \(65.65x \leq 210.08\), it means that the product of \(65.65\) and \(x\) can be less than or equal to \(210.08\). This allows for the values of \(x\) that satisfy the condition of being within Zendaya's budget.
