The elephants at the zoo eat 3 2/3 buckets of bananas each day. The zookeeper bought 7 1/3 buckets of bananas. How many days wil
uranmaximum [27]

Answer: 2 days

Step-by-step explanation:

The monkeys eat 3 ²/₃ buckets of bananas each day. Convert this to an improper fraction:

= 3²/₃ = 11/3 buckets per day

The zookeeper bought 7¹/₃ which is:

= 22/3 buckets

To find out the number of days the bananas will last, divide the buckets bought by the buckets eaten per day:

= 22/3 ÷ 11/3

= 22/3 * 3/11

= 66/33

= 2 days

<em>If dividing fractions, multiply by the reciprocal of the second fraction. </em>

Courtney must earn at least $150 to pay for broken window. She earns $10 for every car she washes.
valkas [14]

Answer:

10c ≥ 150

At least 15 cars (or c ≥ 15)

Step-by-step explanation:

If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.

This equation can be used to express the situation:

10c ≥ 150

<em>To solve you divide the 10 from both sides of the inequality to get.</em>

c ≥ 15
