Hello there! I can help you! The formula for simple interest is prt. We multiply the principal (inital amount) by the interest rate (in decimal form) by the time (could be in months or years). For this expression, our principal is $360. The interest rate is 12.3% (0.123 in decimal form). We will multiply those two numbers first. 360 *12.3% is 44.28. That's $44.28 in interest per year, but we're not done. Now, we multiply that by the amount of time, which is 30 months. In this case, we will convert that to years. 30/12 is 2.5. That is 2.5. We will multiply the interest by 2.5. 44.28 * 2.5 is 110.7. There. The simple interest is $110.70.

Interest = principal * rate * time / 100 = 360 * 12.3 * 2.5 / 100 (Note 30 months = 2.5 years)

Answer is $110.70

Answer:

1.25*x=5/7 and it will take 1.607 gallons maybe

Step-by-step explanation:

we know he used 1.25 gallons to cover only 5/7 of the fence. we don't know the area of the fence. we use a variable for area. 1.25 gallons of paint times the area of the fenxe equaled 5/7 of the fence getting painted. you'd need more paint for the entire fence. solve for x says that x=0.57 was the area. so now we say that 0.57 only equated to 5/7 but we want 7/7 painted so so we need 2/7 more paint so we multiply 1.25 by 2/7 to find how much per for that area and we get 0.357. add 0.357 to 1.25 to get 1.607
