Mary worked from Monday to Saturday last week and bought lunch in the company’s restaurant
every day.
Her lunches cost a different amount every day.
Each lunch cost a multiple of 20¢.
The most expensive lunch of the week cost $7.60 and the cheapest one cost $4.40.
Friday’s lunch cost exactly 11⁄2 times as much as Wednesday’s lunch.
Tuesday’s lunch cost $1.20 more than Thursday’s lunch.
(a) What is the minimum total that Mary’s six lunches last week could have cost?
(b) What is the maximum total that Mary’s six lunches last week could have cost?

Answers

Answer 1

Answer:

25%. 4.80 divided by 1.20 = 4 x 100 = 40o%

Answer 2

Using logical and arithmetic principles, the minimum and maximum total Mary could spend is $31.20 and $40.40 respectively.

Cheapest lunch fee = $4.40 = 440¢Most expensive = $7.60 = 760¢

Minimum total cost of lunch :

Lunch cost will increase steadily by multiple of 20¢ from the cheapest unless given a stated constraint

Monday = $4.80

Tuesday = $4.40 + 1.20 + 0.2 = $5.80

Wednesday = $4.40

Thursday = $5.80 - $1.20 = $4.60

Friday = 3/2($4.40) = $6.60

Saturday = $5.00

Total = $(4.40 + 5.80 + 4.80 + 4.60 + 6.60 + 5.00) = $31.20

Maximum Total :

Lunch cost will decrease steadily by multiple of 20¢ from the most expensive unless given a stated constraint

Monday = $7.40

Tuesday = $7.60 + 1.20 = $6.40

Wednesday = $4.80

Thursday = $7.60

Friday = 3/2($4.80) = $7.20

Saturday = $7.00

Total = $(7.40 + 6.40 + 4.80 + 7.60 + 7.20 + 7.00) = $40.40

Therefore, the minimum and maximum total Mary could spend is $31.20 and $40.40 respectively.

Step-by-step explanation:

the options showing ≥ 25,000 cannot be solutions because the weight must be less than 25,000

if there already is 9200 then that would be added to 80c and, when solved, would tell you how many 80kg containers can be loaded

80c ≤ 25,000 - 9,200

80c ≤ 15,800

Answers

Answer: [tex]P(B|A)=\dfrac{4}{9}[/tex]

Step-by-step explanation:

Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.

Event A is defined as drawing a white ball on the first draw.

Event B is defined as drawing a black ball on the second draw.

P(B|A) is expressed as the conditional probability of occurring B given that A.

i.e. it is the probability of happening B where A is already happended.

If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.

[tex]Probability=\dfrac{Number\ of \ favorable \ outcomes}{Total\ outcomes}[/tex]

$4.32/4=$1.08

$1.04<$1.08

Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.
