Stephen, Gavin and Jim share some sweets in the ratio 4:1:2. Stephen gets 30 more sweets than Jim. How many sweets are there alt

Kamila [148]

Answer:

105 sweets

Step-by-step explanation:

There are 4 + 1 + 2 = 7 parts in total

Stephen gets 4 parts (or 4x)

Jim gets gets 2 parts (or 2x)

Given,

Stephen gets 30 more than Jim, we can write:

Stephen = Jim + 30

4x = 2x + 30

We can solve for "x":

$4x = 2x + 30\\4x-2x=30\\2x=30\\x=15$

There are 7 parts of sweets altogether (or 7x), we know x so:

There are:

7 * 15 = <u>105 sweets</u> altogether
