Answer:
x=7
Step-by-step explanation:
Equate the angles 7x-7 and 4x+14 and solve:
7x-7 = 4x+14
7x-4x = 14+7
3x = 21
x = 7
Given:

2 | ($25 x 2) = $50 | ($11 x 2 + 18) = $40 | Profit = $50 - $40 = +$10
| ---- | -------- | -------
3 | ($25 x 3) = $75 | ($11 x 3 = 18) = $51 | Profit = $75 - $51 = +$24
| ---- | --------- | -------
Total Number of toys = 1+2+3 = 6
Total Earnings = $25+$50+$75 = $150
Total Cost = $29+$40+$51 = $120
Total Profit = $150-$120 = +$30
The summation symbol means we use the variable i in the equation from the given range. In this case, we are given with the equation 3 i - 15 and i ranges from 2 to 7. The summation using simply the calculator is equal to -9. The answer to this problem is -9.
