a bakery sold 10 more cakes this month than it did the last month. It also sold 3 times as many cakes in this month than in the month before the last month. If that total number of cakes it sold in the last 3 months is 116, how many cakes did it sell last month?​

Respuesta :

Answer:

Last month it sold 338 cakes.

Step-by-step explanation:

Let total cakes this month,last month and last 3 months be x,y and z respectively,

x = y + 10...

x = 3z

z = 116

Now, we have to find y,

x = y + 10

or, 3z = y + 10

or, 3•116 = y + 10

or, 348 = y + 10

or, y = 348 - 10

so, y = 338
