This a proportion. The 13.32 is 3/5 the cost so what you'd write first is
<u>13.32</u>=<u>3
</u>   x     5.      Now solve by first multiplying 13.32 by 5 and you get 66.6, and 3 times x. Now you have 66.6=3x. Now divide everything by 3 and you'll get x=22.2. The total is $22.20

13.32  = 3/5
1/5 = 13.32 / 3
1/5 = 4.44
Full cost = 4.44 * 5
= 22.20

Branson and his sister Beatrice combined their allowance of $7 each, so they could buy a movie for $12. They bought $1 container
Andreyy89

Answer:

Step-by-step explanation:

Branson and his sister Beatrice combined their allowance of $7 each. This means that the total amount they had is 7 + 7 = $14

They bought a movie for $12. The amount that they have left is

14 - 12 = $2

They bought $1 containers of fruit salad with the remaining money and split the containers evenly between them. This means that the number of containers that they bought is

2/1 = 2

If they split the containers evenly between themselves, then each person would get

2/2 = 1 container of fruit salad
