Acell phone company charges $45 per month for unlimited calls and $0.25 per text messages. another call phone company $0.15 per text messegaes and $70 per month for unlimited calls. write and solve an equation to evaluate the time the cost from both companies will be the same

You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.
