Yoko, trey, and alan have a total of $115 in their wallets. Alan has 3 times what Yoko has. Yoko has $5 less than Trey. How much
andriy [413]

Answer:

Yoko has $22, Alan has $66, and Trey has $27

Step-by-step explanation:

Let x represent how much money Yoko has.

Alan has 3 times as much as Yoko, so his amount can be represented by 3x.

Trey has $5 more than Yoko, so his amount can be represented by x + 5.

Add these together and set them equal to 115. Then, solve for x:

(x) + (3x) + (x + 5) = 115

5x + 5 = 115

5x = 110

x = 22

So, Yoko has $22.

Alan has 3 times as much, so multiply this by 3:

22(3) = 66

Alan has $66.

Yoko has $5 less than Trey, so add 5 to this:

22 + 5 = 27

Trey has $27.

Yoko has $22, Alan has $66, and Trey has $27

Help with number 13 please and thank youuuuuu
hram777 [196]

Answer:

5+0.80x < or equal to 13

Step-by-step explanation:

5+0.80x < or equal to 13

5 would be your initial fee so that is not going to change. 0.80 is how much you pay for each ride, so that would change depending on how many rides you ride. This added together has to equal greater to or equal than 13, which is how much she has.
