10. $13.43
11. $70
12. Take the percent you pay (100-the discount) as a decimal and multiply it by the regular price.
Step-by-step explanation:
For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22-78. We use this percent byb multiplying the price with a decimal. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.
8. Percent off is 22%. We pay 78%=0.78.
45(0.78)=$35.10
9. Percent off is 33%. We pay 67%=0.67.
89(0.67)=$59.63
10. Percent off is 44%. We pay 56%=0.56.
23.99(0.56)=$13.43
11. Percent off is 75%. We pay 25%=0.25.
279.99(0.25)=$70
12. See explanation above.
Answer:
Step-by-step explanation:
jack=35
Hassan=x
x+35=255
255-35=$220 (It has to be x=)
So:
220/2=$110
Therefore:
Hassan=$110
Jack=$110+$35=$145 (because he had earned $35 more)
Follow the formula Interest=(Principal)(Rate)(Time)
So, the equation would be:
I= 10,000x0.09x5
This equals $4,500
So, the amount of interest is $4,500
