Explanation:

Step1: Calculate value of 130 nickels

A nickel is worth $0.05, so total value = $130 \times 0.05 = 6.5$

Step2: Calculate value of 120 pennies

A penny is worth $0.01, so total value = $120 \times 0.01 = 1.2$

Step3: Sum the two values

Total money = $6.5 + 1.2 = 7.7$

Step4: Generalize for x nickels, y pennies

Value of x nickels: $\$0.05x$, value of y pennies: $\$0.01y$. Total = $0.05x + 0.01y$

Answer:

Total value, 130 nickels and 120 pennies (dollars): $7.70$
Total value, $x$ nickels and $y$ pennies (dollars): $0.05x + 0.01y$
