Question 921922: Need help writing the distributive equation for daughters math.
Marie buys a vest for $38.79 and some four packs of socks. The socks sell for $10.99. If Marie spends $60.77, how many four packs of socks does she buy?
Cannot find correct answer compared to what her equations show.
Thanks.

Build the equation logically according to the values given.

I must assume 1 fourpack of socks sells for $10.99.

Marie's cost, if buying y fourpacks of socks and the 1 vest:
38.79%2B%2810.99%29%2Ay, dollars for the cost.

Marie spent exact-change for the cost.
highlight_green%2838.79%2B%2810.99%29y=60.77%29
You want to solve this equation for y; but more important is to first understand how this equation was created, which has been done here.
