Hello!
to find a percent, convert the percent to a decimal by dividing by 100
13.8 / 100 = 0.138
then multiply the divided percent by the number you needed to find the percentage of
$29.90 * 0.138 = $4.1262
since you're using currency, round the the nearest hundredth
your final answer is $4.13
I hope this helps, and have a nice day!
Answer:
$13.75
Step-by-step explanation:
Bone-shaped treats are 5 for $3.50 at Shelley’s store and Sarah wants to buy 12. She set up and solved this proportion to find how much they would cost. Describe her error and find the correct solution. 5 3.5 = 12 x 3.5x = 60 x = $17.14
<u>5x2=10+3.75=13.75</u>
First, you calculate the total amount of parts : 7 + 3 = 10
Next, divide the number by the total amount of parts : £500 ÷ 10 = £50
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : £50 × 3 = £150 and £50 × 7 = £350
Finally put these answers back into the ratio : £150:£350
To check, make sure both sides of the ratio add up to the original number : £150 + £350 = £500
Answer:
$15.21
Step-by-step explanation:
17% of $13=0.17*13=2.21
13 (the price of the actual lunch) +2.21= 15.21
Alternatively, you can just do the operation:
13*(1+0.17)=15.21
This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip
It’s number 1 it’s a whole number because it has the same numerator and denominator
