Answer:
5 ham sandwiches
Step-by-step explanation:
To find the number of ham sandwiches sold, we should find the pair of numbers that have a difference of 6 and add to 16.
- 1 ham sandwich, 7 turkey sandwiches = 8 sandwiches
- 2 ham sandwiches, 8 turkey sandwiches = 10 sandwiches
- 3 ham sandwiches, 9 turkey sandwiches = 12 sandwiches
- 4 ham sandwiches, 10 turkey sandwiches = 14 sandwiches
- 5 ham sandwiches, 11 turkey sandwiches = 16 sandwiches
While this method isn't always very efficient, it worked pretty well for this case!
Therefore, the answer is 5 ham sandwiches.
One idea is:
Paul wants to buy an iphone X. He has savings of $100 to start with. Local McDonalds pays $7 per hour (after tax) to students on summer break for helping out at the counter. The iphone costs $1000. At least how many hours does Paul need to work at McDonalds to be able to afford the iphone.
So, that matches ax+b>c in that
a is the hourly earning
b is the initial savings
c is the price of the iphone
-10x -120-11x
combine like terms so -10-11= -21x-120
Answer:
The answers to each part are:
Part A.
- <u>The quantity of apples is one-third of the quantity of grapes</u>.
Part B.
- <u>The quantity of apples is a quarter of the quantity of strawberries</u>.
Part C.
- <u>The number of cherries is two-elevenths of the total fruit</u>.
Step-by-step explanation:
To identify the answer in each case, you must remember that all the parts are equal, then:
Part A.
The parts of apples are 1 and the parts grapes are 3, so if you divide the first quantity with the second quantity you obtain:
So, <u>the quantity of apples is one-third of the quantity of grapes</u> or the quantity of apples is three times smaller than the quantity of grapes.
Part B.
The parts of apples are 1 and the parts of strawberries are 4, then you must divide the first quantity with the second quantity:
In this case, <u>the quantity of apples is a quarter of the quantity of strawberries</u> or the quantity of apples is four times smaller than the quantity of strawberries.
Part C.
First, you must add all the part of fruit:
- <em>1 part apple</em>
- <em>1 part orange</em>
- <em>4 parts strawberry</em>
- <em>2 parts cherry </em>
- <em>3 parts grape</em>
The total of fruits is 11 parts, taking into account the quantity of cherries is 2, now you can divide the number of cherries with the total parts of fruit:
- 2 / 11 = 2/11 (two-elevenths)
Now, you can see <u>the number of cherries is two-elevenths of the total fruit</u>.
