You will need to know how much each lunch cost
so
9.40 <span>÷ 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</span>
Answer:
5 × [5(-7)]

= -175
<h3><u>given</u><u>:</u></h3>
base= 25mm
height= 28mm
<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>
the volume of the pyramid.
<h3><u>solution</u><u>:</u></h3>
v= a^2 h/3
v= 25^2 28/3
v= 5833.33333
v= 5833.3mm^3
A=p (1+r/k)^kt
A=500×(1+0.02÷3)^(3×4)
A=541.50
