math - Excel - Multiply Until Total Reached -

-

i want multiply x*y until x>=20, multiply z value , have results displayed 2 values, multiple , multiple*z

the question behind formula is, how many boxes of x capacity need have total capacity of 20 liters , how cost.

x = volume of bottle y = number of bottles in box z = price per box

this done hand, i've been playing (with little effect) in excel while , solution.

i hope makes sense

i rather think formula provided @jeeped for:

i want multiply x*y until x>=20, multiply z value , have results displayed 2 values, multiple , multiple*z

label 2 arrays 1 20 columns , rows shown, populate v1 price per box , in b2: 

=if(and($a2*b$1>20,a2>=20),"",$a2*b$1)

and in x2: 

=if(b2="","",$v$1*b2)

with both formulae copied across 19 columns , 2 sets of 20 formulae copied down 19 rows. result should similar to:

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i need build client web api in vba , needs work behind proxy (with authentication). i've been looking @ winhttp.winhttprequest , msxml2.xmlhttp/serverxmlhttp classes. turns out that: xmlhttp automatically detects proxy settings provided through proxy.pac file (good) winhttprequest doesn't (bad) however, on other hand: xmlhttp automatically follows redirects, , there's no way of disabling behaviour (bad) winhttprequest doesn't (good) since i'd able have cake , eat it, there way automatic proxy configuration component such winhttprequest doesn't follow redirects blindly? the vba-web project might pastry eating problem. https://github.com/vba-tools/vba-web i guess wish go like: dim client new webclient client .baseurl = "https://www.google.com" .proxyusername = <user> .proxypassword = <password> .enableautoproxy = true end dim request new webrequest request .method = webmethod.httpget ...
