Step-by-step explanation:
Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:
Month 1:
Gloria talked on her cell phone for . So, she had to buy 2 packages of for each package.
Hence:
Month 2:
Gloria talked on her cell phone for . So, she had to buy again 2 packages of for each package.
Hence:
Month 3:
Gloria talked on her cell phone for . So, she had to buy 3 packages of for each package.
Hence:
Then, if we take the total Gloria had to pay for the frist three months, we have:
Y = x + 1
y = 1/2x + 3
x + 1 = 1/2x + 3
x - 1/2x = 3 - 1
1/2x = 2
x = 2 / (1/2)
x = 2 * 2/1
x = 4
y = x + 1
y = 4 + 1
y = 5
so ur solution is : (4,5)
