Lena got a prepaid debit card with $20 on it. For her first purchase with the card, she bought some bulk of ribbon at a craft store. The price of the ribbon was 19 cents per yard. If after that purchase there was $12.02 left on the card, how many yards of ribbon did Lena buy

Let's determine the number of yards of ribbon Lena bought by solving the problem step by step.

### Step 1: Set up the equation
Let $ y $ represent the number of yards of ribbon Lena bought.

The total cost of the ribbon is given by:
\[
\text{Cost of ribbon} = \text{Price per yard} \times \text{Number of yards}
\]
Substituting the values:
\[
\text{Cost of ribbon} = 0.19y
\]

Lena had $20 on the card initially and had $12.02 left after the purchase. So, the amount she spent is:
\[
20 - 12.02 = 0.19y
\]

### Step 2: Solve for $ y $
Subtract to find the amount spent:
\[
7.98 = 0.19y
\]

Now, divide both sides by 0.19 to find $ y $:
\[
y = \frac{7.98}{0.19}
\]
\[
y \approx 42
\]

### Conclusion
Lena bought approximately **42 yards** of ribbon.
