Employees at a company are given £1,300 to spend on items for the office. they decide to buy a coffee machine and as many bean bags as possible. bean bags cost £50 with an offer of "buy at least 15 get 20% off the price." the coffee machine costs £370. how much will they have left over from the £1,300?

£10

Step-by-step explanation:

There may be a far easier way to do this, but this is how I did it and still came up with the correct solution.

-Assuming they buy at least 15 bags, they will get a 20% discount.

-20% discount would mean they only pay 80% of the original price. 80%=.80

-let x represent number of bean bags

£50 per bean bag multiplied by sale price .80, plus cost of coffee machine £370 must be equal to or less than £1300.

(50x)(.80) + 370 = 1300

Simplify:

40x + 370 =1300

Subtract 370 from both sides

40x = 930

Divide both sides by 40

X=93/4

Simplify fraction

23 1/4

=23.25

But since they cant buy .25 (quarter) of a bean bag, we reduce* to nearest whole number. We can not increase* to nearest whole number as this would exceed their budget.

23 bean bags. They can buy 23 bean bags at £40 each + coffee machine for £370.

£40(23) + £370 = £1290

£1300-£1290=£10

I hope this helps!

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
