Adrian purchased 20 ballet tickets for a total of $1110.How much would it have cost him for 150 ballet tickets solve using both the rate and proportion methods
:
The rate method finds the cost of 1 ticket times number of tickets required:
1110%2F20 * 150 = $8,325
:
The proportions method, c = cost
20%2F150 = 1110%2Fc
:
Cross multiply
20c = 150*1110
20c = 166500
c = 166500/20
c = $8325
