Chandni has 3 pieces of orange yarn that are 1.25 feet long each and 2 pieces of blue yarn that are 2.75 feet long each. She uses all 5 pieces of yarn for an art project. What is the total length of yarn, in feet, that Chandni uses for her art project

9.25 feet.

Step-by-step explanation:

Given:

Chandni has 3 pieces of orange yarn that are 1.25 feet long each  and 2 pieces of blue yarn that are 2.75 feet long each.

She uses all 5 pieces of yarn for an art project.

Question asked:

What is the total length of yarn, in feet, that Chandni uses for her art project ?

Solution:

By unitary method:

Length of 1 piece orange yarn = 1.25 feet

Length of 3 pieces orange yarn = 1.25 feet 3 = 3.75 feet

Length of 1 piece blue yarn = 2.75 feet

Length of 2 piece blue yarn =  2.75 feet 2 = 5.5 feet

As she uses all 5 pieces of yarn for an art project:-

Total length of yarn, she uses for her art project = 3.75 feet + 5.5 feet = 9.25 feet

Thus, the total length of yarn, she uses for her art project = 9.25 feet.

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!
