Peg and Larry purchased “no contract” cell phones. Pegs phone costs $25 plus $0.25 per minute. Larry’s phone cost $35 plus $0.20
marissa [1.9K]
Let x be the number of minutes Peg and Larry used their phones. So their costs can be written as:

Cost of Peg's Phone usage = 25 + 0.25x
Cost of Larry's Phone usage = 35 + 0.20x

We are to find when the Peg's phone will be more than Larry's phone. We can set up the inequality as:

25 + 0.25x > 35 + 0.20x

Re-arranging the inequality

0.25x - 0.20x > 35 - 25

0.05x > 10

x > 10/0.05

x > 200

Thus, Pag's phone will cost more if the number of minutes of phone usage is more than 200

Factor Completely 5v^2-5v-100
bogdanovich [222]

5 {v }^{2}  - 5v - 100 \\  = 5( {v}^{2}  - v - 25) \\  = 5({v}^{2}   + 4v - 5v - 20) \\  = 5[v(v + 4) - 5(v + 4)] \\  = 5(v - 5)(v + 4)
