(01.02 HC) Marla has $95.50 in her savings account. She deposits $5 every week. Her mother also deposits $20 into the account ev
stepan [7]
Part A:

Variable is a symbol for a number we don't know yet. It is usually a letter like x or y but can be any letter. 
Example: 6z means 6 times z, and "z" is the variable.

Hence, the variables are c and w. [ Choose any one for your answer ]

Coefficient is any number used to multiply a variable.
<span>Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
</span>
Hence, the coefficients are 20 and 5. [Choose any one for your answer]

A constant is a<span> fixed value which does not change regardless of the variables entered.
</span>
Hence, the constant is 95.50

Part B:

Weeks saved (w) = 20

Cars washed (c) = 5

20c + 5w + 95.50 = (20 * 5) + (5 * 20) + 95.50 = 100 + 100 + 95.50 = 295.50

Hence, Marla will have $ 295.50 in her account.

Part C:

In <span>20c + 5w + 95.50, Marla's mom deposits $ 20 after every car wash.

If Marla's mom deposits only $ 10 after every car wash, then, the new equation would be : 10</span><span>c + 5w + 95.50

Hence, the coefficient will change from 20 to 10. </span>
