Answer:
The total money we have to pay is $69.
Step-by-step explanation:
MARKUP is the amount added to the cost price.
MARKUP formula = 100*profit / cost
Cost of the item = $60.00
put the value in the formula
15 = 100*profit/60
profit = 60 × 15 ÷ 100 = 9
the total money is cost + profit
which is 60 + 9 = $69.
So the total money we have to pay is $69.

4(a + 2) + 9 = 5
to solve this problem lets solve this step by step
Step 1 - lets solve this part of problem 4(a + 2 )
by using distributive property we get,
4a + 8 + 9 = 5
Step 2 - adding the like terms
4a + 17 = 5
Step 3 - subtracting 17 from both sides
4a + 17 - 17 = 5 - 17
4a = -12
Step 4 - dividing both sides by 4
a = -3
So our final answer is a = -3
Hope this helps you :)
