Answer:
Total cost =28.575
Step-by-step explanation:
wev are given
total Food cost=$22.50
cameron gave 9% meal tax of his total meal price
total meal price without tax is $22.50
9% of $22.50 will be
9% meal tax=22.50*9/100=2.025
he gave 18% tip of his total food cost without tax that is $22.50
18% of $22.50 will be
18% tip=22.50*18/100=4.05
for total meal cost we will add all costs and total cost will become
Total cost =22.50+2.025+4.05 =28.575
Answer=28.575
Answer:
f^-1 (x) = - 6x-1 / 10 + 9x
Answer:
Jumper, y = 172
Shirt, x = - 105
Step-by-step explanation:
Let :
Shirt = x
Jumper = y
5x + 4y = 163 - - (1)
3x + 2y = 29 - - - (2)
Multiply (1) by 3 and (2) by 5
15x + 12y = 489 - - - (3)
15x + 10y = 145 - - - (4)
Subtract :
12y - 10y = 489 - 145
2y = 344
y = 344 / 2
y = 172
Put y = 172 in (3)
15x + 12(172) = 489
15x + 2064 = 489
15x = 489 - 2064
15x = - 1575
x = - 105
The values ;
Jumper, y = 172
Shirt, x = - 105
We weren't supposed to obtain a negative value, kindly check if the parameters given are correct.
is the formula you need do you divide 47.1 by 2 and
so its aproximatly 7.5 or 7.496
