Answer:
This is an algebraic expression
Step-by-step explanation:
U won't ever use t to mean multiplication u will use a . Or × or a letter next to a number to symbolise mutiplication
The answer to your question is c)15
N*(21/100)=(700/100)
n=(700/100)/(21/100)
n=(700/100)*(100/21)
n=700/21
n=33+1/3
So <em><u>thirty three</u></em> $0.21 pencils can be purchased for $7.00.
25/100 =0.25
10 x 0.25= 2.5
