Your friend has $90 when he goes to the fair. He spends $5 to enter the fair and $15 on food. Rides at the fair cost $1.50 per r

QveST [7]

Easy, if he has $90 in ALL

and he spends $5 and $15

$20 in total

take, 90-20=70

So now he only has $70 left.

If each ride costs $1.50, then he's losing money.

So, y=-1.50x+70

So around the 47th ride he will have no more money.

Please help me with this ratio.

Charra [1.4K]

Answer:

$\frac{inches}{minute}$

Change the feet to minutes by multiplying by 12, and change the hour to minutes.

Speedy: $\frac{240}{60}$

Slowpoke: $\frac{80}{30}$

Cleo: $\frac{96}{10}$

Speedy is the fastest.

$\frac{feet}{hour}$

Speedy: $\frac{20}{1}$
Slowpoke: $\frac{\frac{6.666666667}{.5}}{30}$
Cleo: $\frac{8}{\frac{1}{6}}$

Change minutes to feet by dividing and change the minutes to hours by multiplying.
