This document provides an example of solving an algebra word problem to determine the cost of one snow globe. It defines the cost of a snow globe as x, writes an equation relating the total cost and the cost of the book to x, solves the equation to find that x equals £1.50, and concludes that one snow globe costs £1.50. It also provides guidance to write equations using words instead of symbols and decimals and to use only one equal sign.

1. To Learn And Practice

2. Algebra-
1. Let the number you want to find out be x.
2. Write _x + _ = _
3. The + changes to -. Move it to after the
equal sign.
4. Divide the last number of the equation by
how many x you have.

3. Question
Imelda is at a car boot sale. She buys a book
and two snow globes. The book costs £2.50.
The total cost is £5.50. How much was one
snow globe?

4. Answer
Let the cost of a snow globe be x.
2x + £2.50 = £5.50
2X = £5.50- £2.50
£5.50 - £2.50 = £3.00
£3.00 = 300p
300p divided by 2 = 150p
150p = £1.50
X = £1.50
One snow globe costs £1.50

5. 2x+250=550
2x=550-250
2x=300
X=150
X= £1.50
Don’t use symbols and decimals.
Don’t use more than one equal sign in one
equation.

6. Question
Summer goes to a shopping centre. She has £50
to spend at her favourite shops. Summer
spends £15.75 at ASDA and she spends some
money at Primark. She spends £40.94
altogether. How much did Summer spend in
Primark? How much money does she have left?

7. Answer
Let the money she spends at ASDA be x.
1x + 1575 = 4094
1x = 4094 - 1575
4094 – 1575 = 2519
x = 2519
2529 = £25.19
Summer spend £25.19 in Primark. She has
£9.06 left.
