Answer:B
Step-by-step explanation:
Not sure but the math came out like that.
2/30=0.06 repeated. 0.06=6%. 7% or 6.6% of the 30 families have 4-5 pets.
The initial cost is 189.69. It is marked up 30%.
By simple calculations,
Final cost of the tablet computer = Initial price + 30% of marked price
= 189.69 + (30/100 x 189.69)
This gives us the net value of 245.7. Hence the price of the computer after it's been marked up will be 245.7
