The students in Naomi's class sold calendars for a fund-raiser this year and last year. This year, the selling price of each calendar was 13.25. The price this year represents 6% more than the selling price of each calendar last year. What was the selling price of each calendar last year ?

Answers

Answer 1

Answer: We'll use the variable x to represent last year's price. First, we have to set up an equation:
$.06x+x=13.25$
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:
$.06x+x=13.25 \n 1.06x=13.25 \n (1.06x)/(1.06) = (13.25)/(1.06) \n x= 12.50$

Last year's price was $12.50.

Hope this helps!

PLEASE ANSWER! VERY IMPORTANT LAST IMPORTANT QUESTION! MUST BE CORRECT! POINTS GIVEN! Emma said that when you multiply three negative decimals the answer will be positive. Use these numbers to answer the questions: –2.5, –3.8, –2.7, –4.5, 1.4

Emma changed her statement to say that when you multiply two negative decimals and a positive decimal the answer will be positive. Is Emma’s new statement always true, sometimes true, or always false? Write two equations to support your answer.

Answers

Emma is always. When solving, you use the PEMDAS method going from left to right.

Your equation would be something like " -2 * -2 * 4"
Because you would start with (-2 * -2) = 4 and then move to 4 * 4 = 16

If your equation were something like " -2 * 3 * -2"
You would do -2 * 3 = -6 and then move to -6 * -2 = 12

The sales tax on a $350 computer is $22.75. Find the sales tax rate.

Answers

To find the tax rate when given the initial price of an object and the final tax value, you use the equation: $350 * X = $22.75 (where X is the sales tax rate). Then solve:
$22.75/$350 = .065

So the rate is 6.5%

Mr. Chavis needed to take out a loan for $74,400 for a 2016 XJ luxury Jaguar sedan. If he takes 5 years to pay off the loan at a rate of 5.5%, how much will he pay in interest at the end of the 5 years?

Answers

Mr. Chavis will pay $20,460 in interest at the end of 5 years.

Simple interest will be computed by multiplying the principal to its interest rate and term.

I = P x r x t

P = 74,400
r = 5.5% or 0.055
t = 5 yrs

I = 74,400 x 0.055 x 5
i = 20,460

Increase £2 by fifty percent.(Show working out)

Answers

If I were to increase 2 pounds by fifty percent, I would increase it by half of its value.
Half of 2 is 1, therefore I would increase 2 pounds by 1, thus increasing it to a grand total of 3 pounds. I hope this helps, have a nice day, and if you need more help just ask! :)

First, find out the 50% of £2 then add it to £2 for final value.

It would go in like this -

Increment =50% of £2
= 50/100 × 2
= £1

Now, final value = £1 + £2 = £3
