Kristin spent $120 on shirts. dress shirts cost $40 and t-shirts cost $8. if she bought a total of 7 shirts, then how many of each kind did she buy?

The correct answer is: She bought 2 dress shirts and 5 t-shirts

Step-by-step explanation:

Let's marked dress shirts with x and t-shirts with y.

Now we will make equations to solve this problem:

x + y = 7  =>  y = 7 - x

40 x + 8 y = 120

When we replace y = (7 - x) in the previous equation we get:

40 x + 8 (7 -x) = 120  40 x + 56 - 8 x = 120  => 32 x = 120 - 56 =>

32 x = 64  => x = 64/32 = 2 => x = 2

y = 7 - x = 7 - 2 = 5 =>  y = 5

x = 2 dress shirts

y = 5 t-shirts

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
