Q. Mila has

p

pennies and

n

nickels. She has a minimum of

\$ 1

worth of coins altogether. Write this situation as an inequality.

\newline

Answer:

Convert to Dollars: First, we need to express the value of the pennies and nickels in terms of dollars. We know that $1$ penny is worth $\$0.01$ and $1$ nickel is worth $\$0.05$ . Mila has $p$ pennies and $n$ nickels. Therefore, the total value of the pennies is $\$0.01p$ and the total value of the nickels is $\$0.05n$ .
Combine Total Value: Next, we combine the value of the pennies and nickels to express Mila's total amount of money. The inequality must show that Mila has at least $\$1$ , so we write the inequality as $\$0.01p + \$0.05n \geq \$1$ .
Check for Errors: Now, we check for any mathematical errors in our inequality. The values for pennies and nickels are correctly converted to dollars, and the inequality sign is correctly showing that Mila has at least $\$1$ . There are no math errors in this step.
