Model A has 4GB of storage. Model B has a 25% increase of storage. How much storage does model B have?

4.25GB

Step-by-step explanation:

To get the answer, you must first turn the percentage into a decimal or a number by moving the imanginary decimal from right to left two times before adding it to the given storage of Model A.

25% = 0.25

So, the 25% now becomes 0.25 and can now be added to 4.

4 + 0.25 = 4.25

Thus, the answer will be 4.25GB. Model B has a storage of 4.25GB.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
