Step-by-step explanation:
3km 290m = 3.29km
10 - 3.29 = 6.71km
Shaun invested $176,250 into the new business.
Marcus invested half of the $940,000 so the amount that Shaun and Tristan invested is:
= 940,000 / 2
= $470,000
Shaun and Tristan invested in the ratio 3:5.
The amount that Shaun invested is:
<em>= (Ratio of Shaun / Sum of the ratios) x Amount both invested </em>
= (3 / (3 + 5 )) x 470,000
= 3/8 x 470,000
= $176,250
In conclusion, Shaun must have invested $176,250 into the business.
