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 $320 min$ . So, she had to buy 2 packages of $200 min$ for $\$25$ each package.

Hence:

$(\$25) 2= \$50$

Month 2:

Gloria talked on her cell phone for $243 min$ . So, she had to buy again 2 packages of $200 min$ for $\$25$ each package.

Hence:

$(\$25) 2= \$50$

Month 3:

Gloria talked on her cell phone for $489 min$ . So, she had to buy 3 packages of $200 min$ for $\$25$ each package.

Hence:

$(\$25) 3= \$75$

Then, if we take the total Gloria had to pay for the frist three months, we have:

$\$50 + \$50 + \$75= \$175$

2.8 = 2y What does y equal? 1.4 0.5 2.8 0.6

igor_vitrenko [27]

Answer: 1.4

Step-by-step explanation: First, swap the sides of the equation so that the one with the variable can be in front.

So, its 2y=2.8

To solve this, you simply divide both sides of the equation by 2.

2 divided by 2 is 0. That leaves you with the y by itself. Then, 2.8 divided by 2 is 1.4

So, y=1.4
