On monday the school cafeteria made a collection of $99.55 from paid lunch. the next day 40 students ate at the cafeteria. if the collection of lunch money on monday was $19.95 more how much did the school lunch cost?

99.55 – 40x = 19.95 ; $1.99

Step-by-step explanation:

$1.99

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
