Art [367]
x-\ amount\ of\ candy\ which\ cost\ 5,45\$\\\\y-\ amount\ of\ candy\ which\ cost\ 7,33\$\\\\ 7,33*y+11*5,45=6,14(11+y)\\\\
7,33y+59,95=67,54+6,14y\ \ \ \ | subtract\ 6,14y\\\\
1,19y=67,54-59,95\\\\
1,19y=7,59\ \ \ \ | divide\ by\ 1,19\\\\y=6,38\ pound\\\\

Just need help with C would appreciate it​
IrinaVladis [17]

Answer:

85%

Step-by-step explanation:

The students who read less than six magazines would be placed in the intervals: 0-1, 2-3, and 4-5 on the graph. Adding up the total amount in those intervals gives us:

2 + 15 = 17

So, using the answer from b, we can say that 17/20 kids read magazines. Now, we need to convert it into a percent by multiplying by 100:

17/20 *100

17 * 5

85%
