Answer:
Step-by-step explanation:
1.51 gram to $ 1567.01 = 2.23 gram to $ x
1.51 / 1567.01 = 2.23 / x
cross multiply because this is a proportion
(1.51)(x) = (1567.01)(2.23)
1.51x = 3494.43
x = 3494.43 / 1.51
x = $ 2314.19 <===== what 2.23 grams of gold is worth
==========================
x = first car and y = new car
x = 28,033.51
y = 2x - 301.26
y = 2(28,033.51) - 301.26
y = 56,067.02 - 301.26
y = $ 55,765.76 <====== new car cost
