Jonathan needs two different kinds of socks for school a pair of gym cost 3 and a pair of dress sock cost 5 . If he spent a total of 50 on socks how many of each type of sock did he purchase if the total number of socks is 12

Respuesta :

I wrote down 3g+5d=50 g stands for gym socks and d stands for dress socks. and the numeral next to them is the cost of each. 
I simply substituted numbers that equaled 12 when added and kept guessing till it equaled 50 dollars. I got 3(5)+5(7)=50. 5 Gym socks and 7 dress socks
