Mary Lou spent \frac{5}{6} of an hour, approximately \frac{5}{6}*60 mins=50 mins

Heather invested \frac{9}{10} time compared to Mary Lou, thus she took \frac{9}{10} of 50 minutes, translating to \frac{9}{10}*50=45

Since 45 minutes is shorter than 50 minutes, Heather completed her task quicker while Mary Lou took more time!

Michael uses a blend of dark chocolate and milk chocolate to make the ice cream topping at his restaurant. He needs to buy 100\,
AnnZ [12381]

Answer:

Michael purchases 60 kg of dark chocolate alongside 40 kg of milk chocolate.

Step-by-step explanation:

Let d signify the kilograms of dark chocolate bought by Michael and m signify the kilograms of milk chocolate he acquires.

He must acquire a total of 100 kg of chocolate, thus

d+m=100

With dark chocolate priced at $12 per kg, the cost for d kg would be $12d. The price of milk chocolate is $10 per kg, indicating the cost for m kg is $10m. Michael intends to spend $1,120 on the chocolate, therefore

12d+10m=1,120

Taking the first equation

d=100-m

By inserting this into the second equation:

12(100-m)+10m=1,120\\ \\1,200-12m+10m=1,120\\ \\-12m+10m=1,120-1,200\\ \\-2m=-80\\ \\m=40\\ \\d=100-m=100-40=60

Michael ends up buying 60 kg of dark chocolate and 40 kg of milk chocolate.
