Question

The cost of a toy car is $20 less than 2 times the cost of a toy train. If the cost of toy
car is $100, what is the cost of toy train?

Answer 1

Let the cost of a toy car and that of a toy train be c and t respectively.

Answer 2

Can you set two equations from that?

Answer 3

c = 2t - 20
c = 100
now just sub in 100 for c and solve for t

Answer 4

like this..
100 = 2t - 20
do you know how to solve for t ??
