tory sold 50 balloons for school spirit day. he raised $37.50. he wrote this equation to show how much he charged for each balloon.

= 37.50

what mistake did tory make in writing his equation? what is a correct equation and its solution?
a. he divided b by 50 instead of by 37.50. a correct equation is = 50. its solution is $1,875.
b. he divided b by 50 instead of dividing 50 by b. a correct equation is = 37.50. its solution is $1.33.
c. he divided b by 50 instead of multiplying b by 50.a correct equation is 50b = 37.50. its solution is $0.75.
d. he divided b by 50 instead of setting up a proportion. a correct equation is = . its solution is $1,875.

step-by-step explanation:

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
