Answer:
Step-by-step explanation:
The correct question is
Susan works as a tutor for $10 and hour, and as a waitress for $11 an hour. This month, she worked a combined total of 90 hours at her two jobs. Let t be the number of hours Susan worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month
Let
t -----> the number of hours that Susan work as a tutor
y ----> the number of hours that Susan work as a waitress
z ---> the combined total dollar amount she earned this month
we know that
-----> equation A
we know that
The combined total dollar amount she earned this month is equal to the number of hours that Susan work as a tutor multiplied by $10 plus the number of hours that Susan work as a waitress multiplied by $11
----> equation B
substitute equation A in equation B
therefore
The expression for the combined total dollar amount is $(990-t)
Answer:
10,200 Dollars
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 7500(1 + (0.06 × 6)) = 10200
A = $10,200.00
1. -3/2
2. 2
3. 1/2
4.0
5. 1/2
6. -3/4
7. -1/4
8. -8/11
9. 0
10. -1/5
Brandon's backpack weighs = 3140 grams.
We know, 1000 grams in a kilogram.
Therefore, 3140 grams = 3000 grams + 140 grams = 3 kilogram 140 grams.
Brandon weighs(without backpack) = 22 kg 610 grams more than his backpack.
More than pharse represents addition.
22 kg 610 grams more than backpack weighs = 22 kg 610 grams + 3 Kg 140 = 25 Kg 750 grams.
Therefore, Brandon weighs(without backpack) = 25 Kg 750 grams.
Total weight of Brandon weighs and backpack weighs = Brandon weighs(without backpack) + backpack weighs.
= 25 Kg 750 grams + 3 Kg 140 grams
= 28 Kg 890 grams.
Therefore, Brandon got 28 Kg 890 grams on a scale when wearing his backpack.
