Answer:
The amount of money Angelica will have at the end of five weeks if d = $25 is $175.
Step-by-step explanation:
The given information are;
The allowance Angelica earns for baby sitting = d dollars per week
The amount she receives as allowance = $10 per week
The amount she will have at the end of 5 weeks = (10 + d)·5
The amount, A, of money Angelica will have at the end of five weeks if d = $25 is given as follows;
A = (10 + 25) × 5 = $175
The amount of money Angelica will have at the end of five weeks if d = $25 is $175.
Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.
Answer:
Step-by-step explanation:
X= sales tax %
Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)
Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %
The sales tax is 5%.
Hope this helps! :)
