Answer:
Altogether, they had ?28
Step-by-step explanation:
Had Obi spent only ?12, they would have been even. Thus ?12 is the same as 5-2 = 3 "ratio units". So, each "ratio unit" is worth ?12/3 = ?4.
Then Obi started the day with 5·4 = 20, and Obi started the day with 2·4 = 8. Obi ended with 0, which is 8 less than Rudy.
Altogether, they started with 20 + 8 = 28 of whatever a ? is.
First we have to find 18% of $55.82, which we can do by using the equation 55.82 x 0.18
55.82 x 0.18 = 10.05
so the tip = $10.05
now we just add it to the original bill
55.82 + 10.05 = 65.87
so the total cost = $65.87
Given that the quadrilaterals are similar, we know that:
Substituting the given values, we get:
Solving the above equation for x, we get:
Simplifying the above result, we get:
<h2>Answer:</h2>
It's x>2. I hope this helps you out.
