Answer:

a) CP = SP/1.1

b) CP = $59.50

c) GST = $5.95

Step-by-step explanation:

a) Divide by the coefficient of CP.

SP = 1.1×CP

CP = SP/1.1

b) Use the formula with the given value.

CP = $65.45/1.1 = $59.50

c) You can do this two ways: subtract CP from SP, or multiply CP by 0.1.

GST = SP -CP = $65.45 -59.50 = $5.95

GST = CP×0.10 = $59.50 × 0.10 = $5.95

Thirty students bought pennants for the football game. Plain pennants cost $4 each and fancy ones cost $8 each. If the total bil

sammy [17]

Answer:

number o students bought pennants = 18

number of student bought fancy ones=12

Step-by-step explanation:

Let x be the number o students bought pennants

and y be the number of student bought fancy ones

total 30 students

$x+y= 30$

$y=30-x$

Plain pennants cost $4 each and fancy ones cost $8 each.

$4x+8y=168$

Substitute 30-x for y in second equation

$4x+8(30-x)=168$

$4x+240-8x=168$

$240-4x=168$

Subtract 240 from both sides

$-4x=-72$

divide both sides by -4

x=18

$y=30-x$

$y=30-18= 12$

number o students bought pennants = 18

number of student bought fancy ones=12
