<span>let x be the interval, then:
186 = 50 + 3 + (3+x) + (3+2x) + (3+3x) + (3+4x) + (3+5x) + (3+6x) + (3+7x)
186 = 74 + 28x
x = 4
Eldest son age = 3+7x = 3+28 = 31.</span>
Answer: 18%
Step-by-step explanation: Add 36 + 14 = 50
Then 36*50/100=18
The answer to the question is <span>70.6179775281. which also can be converted to 71.</span>
The purchasing price of the store = $29.25.
They want to resale it at 54% markup of the purchasing price.
54% of 29.25 = 0.54 × 29.25.
On multiplying 0.54 and 29.25, we get 15.795.
Resale price = The purchasing price + Markup
= 29.25 + 15.795.
On adding 29.25 and 15.795, we get 45.045.
We can round it to 45 to the nearest dollar.
<h3>Therefore, the resale price to the nearest dollar is $45.</h3>
