a coffee machine dispenses 8 ounce cups automatically. The amount of coffee may vary by 3%. What are the least and greatest number of ounces the coffee machine may dispense?

3% of 8 is 0.24

so, the max amount would be 8.24 ounces

the minimum amount would be 7.76 ounces

hope this helps!!

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
