1.) The cost of steak at grocery store 1 is $0.75 less per pound than at grocery store 2.

2.) The number of necklace Janet can make in 1 hour = 2.4 to the nearest tenth.

Calculation of equations and amount of necklace

  • In store 2 the cost of 2 pounds = $1.5

But the cost of a pound weight= 1.5/2 = $0.75

Therefore, the cost of steak at grocery store 1 is $0.75 less per pound than at grocery store 2.

The number of necklace made in 20 minutes= 4/5

The number of necklace made in 60mins(1hr) = X

Make X the subject of formula,

X= (60* 4/5) ÷ 20

X= 48/20

X= 2.4 to the nearest tenth.
