Paula and Daniel went to the store to by ingredients for 27 cakes. Paula paid for 2/3 of the cakes and Daniel paid 14 dollars for his portion. How much money did Paula and Daniel spend on their portion of the cake in total?

Answers

so Daniel paid for 1 third because paula paid for the other 2/3
he paid 14 dollars so that's 1/3 of the amount
if you times 14 by 3 you get 42
you times the 13 by 3 because Daniel paid 1/3 you have to times it by 3 to get a whole.
so the answer is that they paid 42 dollars all together.

Daniel paid for 1/3 of the total, b/c they had to pay for the total they had to pay for 3/3 1 whole. Paula paid for 2/3 and Daniel paid for the rest which is the 14 if he paid for 1/3 and Paula paid for 2/3 she paid twice as much as he did. 14x2=28 Paula paid 28 dollars out of the total of total 42dollars it cost

To make a specific hair dye, a hair stylist uses a ratio of 1 1/8 oz of red tone, 3/4 oz of graytone, and 5/8 oz of brown tone. If the stylist needs to make 20 oz of dye, how much of
each dye color is needed

Answers

Answer:

We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:

1 1/8x + 3/4x + 5/8x = 20

2 1/2x = 20

x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.
