Justin bought a calculator and a binder for 15% off the original price. the original price of the binder is $6.20.justin spent a total of 107.27. what was his original price of the calculator

102

to calculate what he spent of the calculator multiple 6.20 by 15 percent of .15 which gives you .93 cents that means 15 percent is 93 cents so you subtract that from the original to get the sale price which is 5.27. subtract this from the total he spent 107.27 and you get 102 so he spent 102 on the calculator. But thats the sale price of if, so the full price must be a little over a hundred. All i did was take 120 multiple it by .15 and figure out that its 18 dollard of meaning that the full price was 120

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
