On rainy mornings, Mo drinks exactly N cups of hot chocolate (assume that N is an integer). On mornings that are not rainy, Mo drinks exactly 3 cups of tea. Last week Mo drank a total of 26 cups of tea and hot chocolate together. If during that week Mo drank 10 more tea cups than hot chocolate cups, then how many rainy days were there last week?
Options:
A) 0  B) 1  C) 4  D) 5  E) 6
T= the number of cups of tea   C= the number of cups of hot chocolate   T+C = 26 T-C=10 -&gt; T= 18. C=8.   Mo drinks 3 cups of tea a day then number of days that are not rainy = 18/3=

<output>6</output>
6   So number of rainy days= 7-6= 
<gadget id="calculator">7-6</gadget>
<output>1</output>
