Answer:
$1.33
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
