Question

Gloria talked on her cell phone for 320 minutes the first month,243 minutes the second month,and 489 minutes the third month.Her payment package dose not allow her pay per minute,She can only buy package.If she has to pay $25 for every 200 minutes,how much did she by for the first three months?

Answer 1

Answer: $\ 175$

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 $320 min$. 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:

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