1 answer:

7 0

45,

because if 1 is proportional to 9, 1 had to be multiplied by 9, so you have to mltiply 5 by 9 to get 45. if 9:45 is simplified by dividing both by 9, you'll see that the ratio becomes 1:5 again. They are equivalent

Answer:

x = $42.8

Step-by-step explanation:

Let

Amount of money shalee has in Sept = $x

Shalee October earnings = $48.24

Total money = $x + $48.24

She spent 3/4 of the money on dress

3/4 of (x + 48.24) = $68.28

3/4 * x + 48.24 = 68.28

3/4x + 144.72/4 = 68.28

3/4x + 36.18 = 68.28

3/4x = 68.28 - 36.18

3/4x = 32.10

x = 32.10 ÷ 3/4

= 32.10 × 4/3

= 128.4/3

= 42.8

x = $42.8
