Michael is going back to school shopping to buy only jeans. He has 130 to spend. He found them on sale for $8 a pair. What is the maximum number he can buy if he needs to save $15 for the Uber ride
home? Write an inequality to represent this situation.

130=8x+15  and 14 pairs

Step-by-step explanation:

Y=mx+b    Since he has 130 dollars to spend, that is Y. He needs $15 to spend for an uber which would be b in an equation. He spends $8/per jean. 130(total)-15(uber)=$115 left. 115(total now)-8x.   8x14=112.  115(left)=112(14 pairs of jeans)

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
