Answer:
A - $10
Step-by-step explanation:
The equation f(x) = 0.50x + 10 is in the form
y = mx + c where m is the gradient and c is the intercept.
The price of the entrance fee will be the intercept because that is when x is equal to 0, meaning it will be $10.
Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
.58 + .15x = 4.78
28 minutes
500 = 200 + 2.50x
x = amount of dessert baskets
500 - 200 = 300.
300 = 2.50x
300 ÷ 2.50 = 120.
Casey made 120 dessert baskets.
Divide 120 by 4 and your answer will be: Rya can drive 30 miles on 1 gallons of gas.
