ratio of boys : girls = 8: 7
8x+ 7x = 195
15x = 195
x = 13
no. of boys = 13* 8=104
no. of girls = 13 * 7=91
Step-by-step explanation:
Let 8x be the number of boys and 7x be the number of girls.
Since the total number of campers is 195 , our equatiom will be
8x + 7x = 195
then solve for x
15x = 195
x= 13
Then substitute x to get no. of boys and girls
no. of boys = 8(13) = 104
no. of girls = 7(13) = 91
