Two donations are in the ratio 5:8. The smaller donation is 35 dollars. Enter the total of both donations in dollars.
Richtige Antwort
91
Erklärung
Five parts are worth 35 dollars, so one part is 7 dollars and the 13 total parts are worth 91 dollars. Adding 8 dollars to the smaller donation would treat a ratio term as a money amount rather than a multiplier.
