Answer:
50 laps
Step-by-step explanation:
20+1.25x+15+2.5x+40+1.5x+25+1.75x=450
7x+100=450
7x+200-200=450-100
7x=350
7x/7=350/7
x=50
Answer:
$1.60
Step-by-step explanation:
<em><u>Write out a proportion. </u></em>
5 bananas/$2 = 4 bananas/$x
<em><u>Simplify the proportion, by cross multiplying. </u></em>
2 times 4 equals 8, then divide 8 by 5, which will give you our variable x.
8/5 is the same as 1.60, so the cost of 4 bananas will cost $1.60.
