The cost of making a gold necklace is $ 10 less than four times the cost of making a diamond ring. If the cost of making a gold necklace is $50 then the total cost of making a gold necklace and a diamond ring
is?​

Answer 1

Answer:

total cost = 65

Explanation:

let the cost of making gold neklace be x and that of duamond be y.

x = 4y - 10

x = 50 (given)

therefore 50 = 4y -10

4y = 60

y = 15

total cost = 50 + 15 = 65
