you will need to know how much each lunch cost
so
9.40  ÷ 4  =  2.35
so each  lunch cost 2.35 dollars

now we need to find out how much it will cost for 10 lunches

10 x 2.35 = 23.5

so for 10 lunches it will cost 23.5

We have an equation: 4/10= 9.40/?

Cross multiply:
4? = 9.4010
⇒ ?= 9.40*10/4= 23.5

10 students would spend $23.50 on the same school lunch~
