i give the brainliest answer for the people answer

Write an expression for the amount she added:

Dimes: 2(0.10)

Quarters: 3(0.25)

Nickels: 6(0.05)

Now write an expression for what she took out:

Quarters: 2(0.25)

Dimes: 5(0.10)

Now combine them:

2(0.10) + 3(0.25) + 6(0.05) - 2(0.25) - 5(0.10)

Simplify:

0.20 + 0.75 + 0.30 - 0.50 - 0.50

1.25 - 1.00 = 0.25 increase.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
