Mr. mckay bought b boxes of crackers for $3 each and p pounds of cheese for $4 per pound. how much did he spend in all?

The total amount he spend is:

                  $ (3b+4p)

It is given that:

Cost of 1 box of crackers= $ 3

This means that the cost of b boxes of crackers= $ 3b

Also,

Cost of 1 pound of cheese= $ 4

This means that the cost of p pounds of cheese= $ 4p

Hence, the total amount he spend=

Cost of b boxes of crackers+Cost of p pounds of cheese.

=   $ 3b+$ 4p

= $ (3b+4p)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
