Answer:
6
Step-by-step explanation:
18-3 = 15. 15 divided by 2.5 is 6. Hope this helps!
The equation would look like: p - 5.16 = 15.48
because the coupon subtracts 5.16 from p and the price you pay is 15.48
Solve the equation by adding 5.16 to both sides
p = 20.64
The original price of the shirt is $20.64
You are given
a commission of $10 for $100 in sales. You are to find the commission for $150
in sales. It is stated in the problem that the salesman’s commission varies
directly as his sales. Directly means proportional, and so this relationship has
a constant. Let us say the salesman commission is c and his sales is s. Let us
also denote k as our constant.
C = ks
$10 = k($100)
k = 0.1
We need to find
the salesman commission in $150 sales.
C = ks
C = (0.1)($150)
<u>C = $15</u>
The answer is 7.
To prove whether this is correct or not, just test it with the given conditions,
7x4+4=46.
Does 2x23=46?
Yes.
So, therefore,
The answer is 7.
