He bought 24 flowers that were a combination of roses and tulips. roses cost $3.00 each and tulips cost $1.25 each. he spent $58.00. how many of each flower did he buy?

Since tulips cost $1.25 each, and he spent a total of $58 (integer), the number of tulips bought must be a multiple of 4, i.e. 4 for $5 (instead of 4 roses for $12, a difference of $7).

If he bought ALL roses, it would have cost him 24*3=$72.

He spent $72-58=$14 less, so change 8 roses for 8 tulips for $14 less, i.e.

16 roses, and 8 tulips, check: 16*3+8/4*5=48+10=$58.

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
