Ahmed spent 2/3 of his money on a burrito and a water. The burrito coast 2 times as much as the water. The burrito cost $4, how much money does Ahmed have left?

Answers

The burrito costs twice as much as water. Let's assume the water costs $w
$4=2w
w=$2 
Ahmed spent $2+$4=$6
2/3 of the total amount = $6
Total amount =$6x3/2
                      =$9
if a burritto is twice as much as water the the water is two dollars. if Ahmed spent 2/3 of his money then( 4+2=6) for burrito and water it means he had nine dollars originally so he is left with 3 dollars.  

Jana and her friend bought 4 hamburgers, 3 orders of fries, and 2 milk shakes for $3 each. They paid for the food with $20. Which part of the equation represents the total cost of their items? Justify your answer. c = $20 - (4h + 3f + 6)

A) $20; They paid $20 for the food.
B) (4h + 3f); Find the total cost by adding the price of 4 hamburgers to the price of 3 fries
C) 4h + 3f + 6; Find the total cost by adding the price of 4 hamburgers to the price of 3 fries to the price of 2 milkshakes.
D) c = 20 - (4h + 3f + 6); Find the total cost by subtracting the price of 4 hamburgers to the price of 3 fries to the price of 2 milkshakes.

Answers

For this case we have the following variables:

h: Cost of each hamburger bought by Jana and her friend

f: Cost of each order of potato chips bought by Jana and her friend

b: Cost of each milkshake

If you bought 4 hamburgers, 3 orders of potatoes and 2 milkshakes, you have a cost of:

Cost = 4h + 3f + 2b

It is known that each shake costs $ 3, sob =3$

Substituting we have:

Cost = 4h + 3f + 2 * 3

Cost = 4h + 3f + 6

Thus, the total cost is given by:

Cost = 4h + 3f + 6

Answer:

Cost = 4h + 3f + 6

Ms. Aniston asked seven students in her class to collect pet food cans for a local animal shelter. The dot plot shows the number of food cans collected by each student. Each dot represents one student. What is the median of the data set? A. 9 B. 7 C. 6 D. 8

Answers

Answer: The answer is going to be 7

Step-by-step explanation: So for this problem it is important to know what a median is. The median is essentially the center number when everything is written out. So you want to take your line plot and write out each number on the bottom as many times as a dot appears above it. For this problem that would look like 6, 6, 7, 7, 8, 9, 9. Since you have seven numbers the center would be the 4th one. In ascending order out of these numbers the 7 occurs fourth thus giving you your answer.

Solve i=prt if i=105, p=700 & r=0.05

Answers

assuming you're trying to find t, first you would plug in the numbers given to get 105=(700)(.05)t
next, you multiply p and r to get 105=35t
after that, you divide the 105 by 35 to get the final answer of t=3
