Quartz Beads
Algebra 2 word problem?
A shop sells jewelry of amber beads and quartz. For amber beads 4 and 4 grains of quartz, the cost is $ 46.00. For amber grain quartz 1 and 3 account, the cost is $ 14.50. Find the price of each type of grain.
a = b = amber quartz Make a system of equations: April 4 b = 46 a, b 3 = 14.50 Solve for each variable, I'm using the substitution of a 4-3b 14.50 (14.50-3b) 4 = b = 46-12b 58 4 b = 46 = 46 -12 = 58 8b 8 B b = $ 0.66 Plug March 1 +3 b = 14.50 (0,66) = 14.50 a = 12.5 So if I did this right would be $ 12.50 for amber, $ 0.66 for quartz hope helped:)
