Hey there,
Question #1
So, we need to find the cost of the 4 pens which ended up to be 3.48 because of tax. So when we divide 4 ÷ 3.48, this would conclude to be ¢0.87 for each pen.
Question #2
So, what I will do is I will subtract 3 from $1.70 and that would give me $1.40.
So this would be that there are ( 4 quarters) and he had (7 more dimes) so 4+3 would equal 7
Question #3
The baby would be around 15 weeks old because by doing 0.17 and over and over again until I get 5.75.
Hope this helps.
