Answer: 5
Step-by-step explanation:
Given: Melissa exercises for 20 minutes every day.
She decides to increase her daily exercise time by 5 minutes each week.
Let x be the number of weeks can Melissa increase her exercise time this way.
Then according to the question, we have the inequality as :_
Hence, the number of weeks can Melissa increase her exercise time this way = 5.
Tayna bought 3 items that all share the same price.
So, we will call this 3x. Where x = a price.
Then Tony bought 4 items that each cost the same amount, but each was $2.25 less than the items that Tanya bought. So, we will call this 4(x - 2.55).
We put parentheses around the x and 2.55 because x = the price and Tony's items all are $2.55 less than Tanya's.
Now lets put the equation together and solve this.
3x = 4(x - 2.55)
It has an equal sign because both paid the same amount of money.
Let's do the distributive law of property with the 4.
3x = 4x - 10.2
-x = -10.2
Transpose the 4x.
Because both are negative, it's actually positive.
x = 10.2
Now let's substitute the x in the equation to see if it fits!
3(10.2) = 4(10.2 - 2.55)
After doing the work it comes out as 36=36.
But now back to the original question. What is the individual price for each person?
We know that Tayna's price for each item is $10.2. But what about Tony's?
Well in the question it said it's $2.55 less than Tayna's items.
$10.2 - $2.55 = $7.65
So, each of Tony's items is $7.65.
