The cost for roberta's college next year is $11,000. she has a grant for $1,500 and a scholarship of $5000. she plans to earn 40% of the remaining amount. how much will still be left to pay?

She will have to pay $2,700.
She is starting with a bill of $11,000. If we subtract the 1500 grant and 5000 scholarship, she has left a bill of 4500.
She is going to earn 40% of it, so she still have to pay 60% of it. 
0.6 x 4500 = 2700

You need to use the logical equivalence lawsin this problem you have to use definition of implication(~p v q)i hope this
