Carrie was given ten twenties and 140 quarters by her aunt to use for lunch. If she spent all the quarters and 3/5 of the twenties, calculate the total amount of money she paid for the lunch.
Give me a solution to this problem
Since she spent all the quarters, she paid her lunch partly by quarters totaling 140*$0.25 = $35
She also used 3/5*10 = 6 of the twenties to pay for the lunch.
The total amount of the twenties that she used is 6*$20 = $120
She spent $120+$35 = $155 on the lunch.
