Ana has chosen a mobile phone plan that consists of a fixed payment of S / 30 per month, which includes 100 minutes of calls and 200 text messages. In addition, each minute and text message additionally, a recharge of S / 0.17 and S / 0.04, respectively. Which expression changes to calculate the consumption of a month? How much will Ana pay for a consumption of 226 minutes and 317 text messages?

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
