The answer is 13
Euler's formula:
F + V - E = 2
F - number of faces
V - number of vertices
E - number of edges
We have:
F = 7
V = ?
E = 18
7 + V - 18 = 2
7 + V = 2 + 18
7 + V = 20
V = 20 - 7
V = 13
$20 base fee + ($1.50 per hour × X hours rented) = Y the overall price
20+(1.50×X)=Y
Example:
Let's say the golf cart is rented for 3 hours.
X = 3
$20 base fee + ($1.50 per hour × 3 hours)
20+(1.50×3)
20+4.50= $24.50
So in this example Y=$24.50
$55 this is shown by doing 80/100=0.80. and 0.80*55=this is the answer
So you divide $27.09 by 7 to get red grapes price which is $3.87. Dividing $14.96 by 4, you get $3.74. So red grapes are most expensive.
