Marco still owes his brother $105. You get this answer by doing the following: Start by multiplying 150 * 0.3 (This is the same as multiplying by 30%). You will get 45 for your answer. This number is how much Marco has paid his brother so far. Then subtract 45 from 150 (150-45) to find out how much more Marco has left to pay. Your final answer will be $105.
Answer:
1/4
Step-by-step explanation:
So, we can create this representation of a in relation with b, since we know a is smaller than b by 1/5 of b, we can say that a is equal to 4/5 of b, right?
To invert the ratio, we need to isolate B, so we multiply both sides of the equation by 5/4
So, we have b being 1/4 bigger than a.
I’m sorry I don’t see I picture what do you need help with? Anything?
Answers:
- Sarah has $12.50
- Sam has $27.50
- Casey has $55
======================================================
Explanation:
x = amount of money Sarah has
x+15 = amount of money Sam has, since he has $15 more than her
2(x+15) = amount of money Casey has, since he has twice as much as Sam.
Let's add up those three expressions and set that sum equal to 95
Solve for x.
Sarah + Sam + Casey = 95
x+(x+15) + 2(x+15) = 95
x + x + 15 + 2x + 30 = 95
4x+45 = 95
4x = 95-45
4x = 50
x = 50/4
x = 12.50
This says that Sarah has $12.50
That must mean Sam has x+15 = 12.50+15 = 27.50 dollars
And Casey must have 2*27.50 = 55 dollars.
----------------
As a check,
Sarah+Sam+Casey = 12.50+27.50+55 = 95
So the answer is confirmed.
