Evas cell phone plan allows her to send up to 125 text messages per month. If she sent 90 texts so far, what percent of her monthly message limit has she used?

72%

Step-by-step explanation:

We know that the milit of text messages is 125, so this number is the 100%.

We can represent this as follows:

Text messages Percentage

125 ⇒ 100%

and we want to know what porcentage is 90 text, also i will call this unknown porcentage x:

Text messages Percentage

125 ⇒ 100%

90 ⇒ x%

To solve this problem we use the rule of three: we multiply the cross quantities on the table (100% and 90) and divide that by the remaining amount (125):

x% = (100%) (90) / 125

x% = 9000% / 125

x% = 72%

The percentage of her monthly message limit used=71%

Step-by-step explanation:

Step 1: Determine maximum limit and limit used

The maximum text messages Eva can send=125 texts

Total number of text messages used=90 texts

Step 2: Express percent of her monthly message limit has she used

p = (u/t) * 100

where;

p=the percentage of her monthly message limit used

u=the number of texts messages already used

t=total number of message limit per month

In our case;

p=unknown

u=90 texts

t=125 texts

replacing;

p = (90/125) * 100=72%

The percentage of her monthly message limit used=71%
