Constance is saving money to buy a new bicycle that costs 195.75.she already 40 saved and plans to save 8 each week. how many weeks will take her to save enough money to purchase the bicycle?

20 Weeks

195.75-40=155.75

155.75÷8=19.46875

Answer

20 weeks

Step-by-step explanation:

given total is 195.75 that she needs.

she has 40

so you take 40 from the 195.7 = 155.70

you are then told she will save an additional 8 each week

and they want to know how many weeks it will take

155.70/8 a week = 19.46 weeks to gain enough money

i would imagine you will need to round up b/c it will take that 20th week to have the remaining balance

check work:

total needed 195.70

has 40

8 a week multiplied by nineteen weeks = 152.00

remaining needed is  3.70 meaning one more week

195.70

-40

-152

= 3.70

1 more week needed so 20 weeks total to save

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
