Students bought 32 copies of Amazing Science for a total cost of $95.36 and 32 copies of Sci-Fi for a total cost of $110.40. If each student bought 1 copy of each magazine, how much did each student spend?

$6.43

Step-by-step explanation:

Students bought 32 copies of Amazing Science for a total cost of $95.36 and 32 copies of Sci-Fi for a total cost of $110.40. If each student bought 1 copy of each magazine, how much did each student spend?

For Amazing science:

$95.36 = 32 copies

Therefore,

1 copy = 1 student

Hence:

32 student = $95.36

1 student = x

Cross Multiply

32x = $95.36

x = $95.36/32

x = $2.98

For Sci fi

$110.40 = 32 copies

Therefore,

1 copy = 1 student

Hence:

32 student = $110.40

1 student = x

Cross Multiply

32x = $110.40

x = $110.40/32

x = $3.45

Hence, each student spent

$2.98 on Amazing Science and $3.45 on Sci Fi magazines.

The total amount they spent

= $2.98 + $3.45

= $6.43

Therefore, If each student bought 1 copy of each magazine, each student spent $6.43

answer:  

123455421

step-by-step explanation: easy

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
