Answer:
247 cards
Step-by-step explanation:
Misha : Carlos = 9 : 4
Carlos = 76 cards
Misha = x cards
9 : 4 = x : 76
9/4 = x/76
Cross product
9 * 76 = 4 * x
684 = 4x
x = 684 /4
x = 171
Misha = 171 cards
how many cards do they have together?
Total cards altogether = Misha + Carlos
= 171 cards + 76 cards
= 247 cards
Total cards altogether = 247 cards
