Acarnival charges $1.50 per ride after an entrance fee. you paid a total of $30
after 12 rides. (a)write an equation that gives the total cost as a function of the
number of rides. (b) find the total cost for 19 rides.

I didn't really understand but I hope this helps sorry if it doesn't!!

Step-by-step explanation:

r = number of rides

1.50r

1.50×12=18

1.50×19=28.50

12 rides = $18

19 rides = $28.50

and if you need the entrance fee:

30-18=12

so it would probably be $12.

and for the total ig fo the last one it would be:

28.50+12=40.50

so $40.50

Again I didn't really understand the question but I hope this helps!!

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
