The answer is Letter B - $2,850.
Multiply the number of shares to their respective costs per share. Add the results. Get the total number of shares then divide it by 10 before multiplying the result to 4.25. Add the product to the previous total.
Hyren Airlines: 92 shares x 13.70 = 1260.4
Giaco Household Goods: 130 x 3.28 = 426.40
Iwad Records: 126 x 8.06 = 1015.56
Total: 2,702.36
Commission: (92 + 130 + 126) 348 shares / 10 shares = 34.8 x 4.25 = 147.90
Total: 2702.36 + 147.90 = 2,850.26 or 2,850
Answer:
8 hours
Step-by-step explanation:
Step one:
Given data
Tom earned $72 walking dogs for 6 hours
amount earned = $72
time taken = 6 hours
Required
The time taken to earn $96
Step two:
let us find the unit rate of his earning
unit rate = 72/6
= 12 per hour
In 1 hour Tom earns $12
in x hours he will earn $96
cross multiply we have
96*1= 12x
divide both sides by 12
x= 96/12
x=8 hours
Answer:
Step-by-step explanation:
Both expressions are examples of the <em>distributive property</em>, which basically says "if I have <em>this </em>many groups of some size and <em>that</em> many groups of the same size, I've got <em>this </em>+ <em>that</em> groups of that size altogether."
To give an example, if I've got <em>3 groups of 5 </em>and <em>2 groups of 5</em>, I've got 3 + 2 = <em>5 groups of 5 </em>in total. I've attached a visual from Math with Bad Drawings to illustrate this idea.
Mathematically, we'd capture that last example with the equation
. We can also read that in reverse: 3 + 2 groups of 5 is the same as adding together 3 groups of 5 and 2 groups of 5; both directions get us 8 groups of 5. We can use this fact to rewrite the first expression like this: 
.
This idea extends to subtraction too: If we have 3 groups of 4 and we take away 1 group of 4, we'd expect to be left with 3 - 1 = 2 groups of 4, or in symbols: 
. When we start with two numbers like 15 and 10, our first question should be if we can split them up into groups of the same size. Obviously, you could make 15 groups of 1 and 10 groups of 1, but 15 is also the same as <em>3 groups of 5</em> and 10 is the same as <em>2 groups of 5</em>. Using the distributive property, we could write this as 
, so we can say that 
.
