Hunter and Logan built small sand towers on the beach. Hunter built 20 towers, and Logan built 9 towers. Then, the ocean water came up and knocked down 6 of the towers. How many of the boys' sand towers were left standing?

23

Step-by-step explanation:

Given:

Hunter and Logan built small sand towers on the beach.

Hunter built 20 towers, and Logan built 9 towers.

Then, the ocean water came up and knocked down 6 of the towers.

Question asked:

How many of the boys' sand towers were left standing?

Solution:

Number of towers made by Hunter = 20

Number of towers made by Logan = 9

Total towers made by both = 20 + 9 = 29

Number of towers knocked down by the ocean water = 6

Remaining number of towers = 29 - 6 = 23

Thus, 23 sand towers of the boys were left standing.

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!
