Question

Krystal and Sarawong are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and packages of crocus bulbs. Krystal sold 6 packages of tulip bulbs and 5 packages of crocus bulbs for a total of $135. Sarawong sold 12 packages of tulip bulbs and 4 packages of crocus bulbs for a total of $180. What is the cost each of one package of tulips bulbs and one package of crocus bulbs?

Answer 1

for K: 6T + 5C = 135

for S: 12T + 4C= 180 where t is the cost of tulips and C is the cost of crocuses

Multiply the 1st equation by 2:12T + 10C = 270

Subtract: 6C=90 and C=15

You take it from here.
