this is how to represent it and it is a direct variation.
Answer:
$30.53
Step-by-step explanation:
Find total sum
30+25+35=90
90+24=114
114+40=154

458/15=30.53333
Answer:
$298
Step-by-step explanation:
Profit = Income - Cost
2 tires for 35 each, so total cost is 2*35=70. Sold for 65 each, so income is 2*65=130. Profit is 130 - 70 = $60.
3 rims for 75 each, so total cost is 3*75=225. Sold 136 each, so income is 3*136=408. Profit is 408 - 225 = $183.
5 headlight covers for 4 each, so total cost is 5*4=20. Sold for 15 each, so income is 5*15=75. Profit is 75 - 20 = $55.
Total profit = 60 + 183 + 55 = $298
Here's a graph of those terms.
