Marcela has 4 qauaters ,2 dimes,2nickels,3 pennies .how much money does marcela have in all?

$1.33

Step-by-step explanation:

First, lets write out all of the coins as decimals, so its easier to work with.

Quarters are .25 cents

Dimes are .10 cents

Nickles are .05 cents

Pennies are .01 cents.

If she has 4 quarters, thats the same as having .25 cents x 4.

.25 times 4 is 1.00, so we know she has $1.00 just from the quarters.

She has 2 dimes. This is the same as .10 x 2, which is .20

Now we add that to the $1.00 she has from quarters, so we are at $1.20

She has 2 nickles, which is .05 x 2, or .10. Add that to the $1.20 to get $1.30

She has 3 pennies which is .01 x 3, or 0.3. Add this to $1.30 to get $1.33

So Marcela has $1.33 in total

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
