Bananas are $0.49 per pound, and you want to buy 5.5 pounds of bananas.
0.49 x 5.5 = 2.695 <span>≈ 2.70
</span>
So the final answer is 2.70 dollars for 5.5 pounds of bananas.
You can solve this by using the expressions 12+23 and 12-23.
12+23=35
12-23=-11
35 and -11 are 23 units away from 12 on a number line.
⇒The answer to the first question would be $69.75.
⇒The answer to the 2nd question would be $36.48.
⇒The answer to the 3rd question would be $42.7.
Here's how to get them:
For question 1: A 55% markup for $45 ⇒1.55*45⇒69.75
For question 2: A 60% markup for $22.8⇒ 1.6*22.8⇒36.48
For question 3: A 40% markup for $30.50⇒1.4*30.50⇒42.7
Small Explanation: The reason why there should be a 1 in front of the decimal (which is the percent, but in decimal form) is because by not adding that number 1 in front of the decimal, you will have to do an extra step.
Anyway, hope this helped! :-)
Answer:
102 textbooks
Step-by-step explanation:
From the above question,
The total amount in donations = $4,111 . They plan to use the money to buy new social studies textbooks. Each textbook costs $40.
If :
$40 = 1 textbook
$4,111 = x text books
Cross Multiply
40 × x textbooks = $4,111 × 1
x = $4,111/40
x = 102.775 textbooks
Since the number of textbooks is whole number and it cannot in be decimal, the number of textbooks they can purchase is 102 textbooks
