Hi MRS I worked out $5 - 1.10 = 3.90 bs $5 - $2 = $3 + 90 = $3.90.
ReplyDelete$10 - 4.60 = 6.40 bs $10 - $4 = $6 + 40 =6.40
So I worked out that S 5-S 1.10=? S 5- S 1=4 S 4-10c=3.90 answer is 390
ReplyDeleteSo i word out that 10-?=4.60 10-5=5 5-40=4.60 so the answer was 4.60

ReplyDeletemary had 5.00 and a choc attack bar costs 4.90 so 5.00-1.00-400 4.00-0.10=4.90
ReplyDeleteHine has 10.00 and she get's 4.60 change so 4.60+0.60=5.00 5.00+5.00=1.00

This is my strategy that I done but I think it is wrong but I don't know.
ReplyDeleteNumber 1:
So first I done Mary has $5
And then I wrote Choc Attack is $1.10
Then the last bit I done was $1.10 + $3.90=$5
Number 2:
First I done Hine has $10
Then I done She gets $4.60 change
Then the last bit I done was $10 - $6.40=$4.60
And that was all I done Hope you like it:)
The first question is she had $5 and the change that she got back was $4.90.
ReplyDeleteThe second one the buiscuits were $5.40
the third answer is $2.00
From Quinaln and Antonia
This is the way I solved the question 3. It said she had 1.10 and 90 cents. 1.10 + 90 cents = 2.00. So she had $ 2.00. The chips were 1.10. So then I did $ 2.00 - 1.10 which equaled 90 cents. So she put 1.10 in the vending machine and got back 90 cents.

$5 - Mary
Bar of chocolate - 1.10
$5 - 1.10 = 3.90
Hello it's me Liz and Jess,
ReplyDeleteThis is how we solved the problems. We started with question one and this is how we solved it we did $5-$1=$4 and then we did ten cents+90 cents=$1 and so we add the answear is $4.10.
from jess and Liz
1. 5-1=4 , 10c-4=3$ and 90c.
ReplyDelete2. 4$ and 60c+40c=5$ , 5+5=10, 5$ and 40c.
Mary has $5 - $1 and 10c = $3 and 90c
ReplyDeleteHine has $10 - __= $4 and 60c and the answer is $5 and 40c
Tai bought a chip and and he got back $1 and 10c so he wasted 20c and got back 90c
