Hey there. So basically, find out how much the pencils and notebooks cost first.
The notebooks cost = $3.25
The pencils cost = $0.50

Then, think about what you need to figure out in this problem.
Jake has $20. You need to find how many notebooks Jake can buy in maximum after buying 8 pencils.

If Jake buys 8 pencils that costs $0.50 each, he spends $4 on the pencils.

So now, to find out how many notebooks he can buy, do 20 minus 4.
Jake's got $16 left.

If the notebooks cost $3.25 each, we need to find out how many notebooks he can buy by dividing them. So, 16 divided by 3.25 equals 4.923... and so on.

That means, Jake can buy 4 notebooks with his remaining money.

Dyna has ran 3 km of her race. If she is 65% of the way done. how long is the race altogether? Round to the nearest tenth.

Eddi Din [679]

Lets say the race is x km long.

That means she ran 65% of x.

And that also means that 65% of x = 3

So 65%*x=3

65/100x=3

x=3*100/65

x=300/65

x=4.62
