An international calling plan charges a rate per minute plus a flat fee. a 10-minute call to france costs $3.19. a 15-minute call to france costs $4.29. write and solve a linear equation to find the cost of a 12-minute call to france

y = 0.22(12) + .99 = 3.63

A 12 minute call will cost $3.63

do you mean add both of the equations together

because if you do the answer is 10x-5
