Ray has $36 to buy masonry nails and finishing nails for his project. masonry nails sell for $5.50 per box, and finishing nails cost $3.50 per box. only full boxes are available for purchase. if ray buys 3 boxes of masonry nails, what is the maximum number of boxes of finishing boxes he can buy?

5 boxes

Step-by-step explanation:

Given that;

The total amount Ray has with him to buy masonary nails and finishing nails for his project is $36

If Masonry nails sell for $5.50 per box

Finishing nails cost $3.50 per box.

Now, Only full boxes are available for purchase.

If Ray buys 3 boxes of masonry nails

i.e 3 × $5.50 = $16.5

what is the maximum number of boxes of finishing boxes he can buy?

To determine the number of finishing nails boxes he can buy. we will subtract the expense spent on the prior 3 masonary nails from his total amount

i.e $36 - $16.5

= $19.5

Let's not forget that, only full boxes are available for purchase and not half or quarter.

SO since 1 finishing nail box cost $3.50

then let x finishing nail box cost $19.5

∴ (x) × $3.50 =1 × $19.5

(x) =

(x)  = 5.57 boxes

Since full boxes are available for purchase then   (x)  ≅ 5 boxes, then Ray will be left with $2 at his pocket.

Therefore, the maximum number of boxes of finishing boxes he can buy is 5 boxes

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
