Answer: so she bought 3 pens
Step-by-step explanation:
.90 times 6 = 5.40
then you take 1.20 times 3 = 3.60
then take 5.40 + 3.60 = 9
Answer:
3 pens
Step-by-step explanation:
First you need to find out how much did the 6 pencils costs.
To find this out you need to multiply 6 by $0.90 because each pencil costs 90 cents.
So 6* .90 = $5.40
Now you need to subtract $5.40 from $9 to find out how much money you had left to buy pens.
$9 - $5.40 = $3.60
You had $ 3.60 to spend on pens so to figure out how many pens you bought you need to divide $3.60 by $1.20 since each pen costs $1.20.
So 3.60/1.20 = 3
You bought 3 pens and 6 pencils for $9
