Ajeweler had a fixed amount of gold to make bracelets and necklaces. the amount of gold in each bracelet is 7 grams and the amount of gold in each necklace is 20 grams. the jeweler used 109 grams of gold and made 4 more bracelets than necklaces. determine the number of bracelets made and the number of necklaces made

7 bracelets and 3 necklaces

Step-by-step explanation:

109=7x+20y

109=7(7) + 20(3)

109=49 + 60

109=109

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
