Answer:
$337.50
Step-by-step explanation:
The computation of the number of miles need to drive for determining the same cost is given below:
Let us assume the miles be x
So for the first plan, the equation is
= $0.90x
And for the second plan, the equation is
= $75 + $0.70x
Now equate this
0.90x = $75 + 0.70x
0.90x - 0.70x = $75
0.20x = $75
x = $75 ÷ 0.20
= 375 miles
Now the same cost would be
For plan A and plan B
0.90x = $75 + 0.70x
0.90(375) = $75 + 0.70(375)
$337.5 = $75 + $262.50
$337.50 = $337.50
Given:
c = cost
p = people
Spent $300
Formula: c=5p+215
Solving for how many people (p)
C=5P+215
(300)=5P+215 (Subtract 215 on both sides)
85=5P (Divide by 5 on both sides)
17=P
The answer is 17. 17 people can afford to host a birthday party.
