Question 1100046: Caitlyn got a 559-peso plan for her new cellphone. This plan covers all calls and texts to Globe, but none for other networks. It costs a peso per minute per text to other networks. Write the equation that signifies this relationship. Let Y be the amount of money to be paid per month and X the number of texts to other networks. How much does she have to pay if she sent 195 texts to Sun and 120 texts to Smart?

she pays 559 a month plus 1 peso per text to other networks besides globe.

formula is y = 559 + 1 * x

x is the number of texts to networks other than globe.
the charge is 1 peso per text.

if she sent 195 texts to sun and 120 texts to smart, then she had a total of 315 texts to networks other than globe.

her monthly charges would be y = 559 + 1 * (120 + 195) = 559 + 1 * (315) = 559 + 315 = 874.
