Ashopper needs 24 sandwich rolls. the store sells identical rolls in 2 differently sized packages. they sell a six pack for $5.28 and a four pack for $3.40. should the shopper buy 4 six packs or 6 four packs?

The best deal is the pack of 4.

Step-by-step explanation:

A shopper needs 24 sandwich rolls.

The price of the six pack is $5.28 . If the shopper buy a pack of 6, so he needs to but 4 of this as he needs 24 in total.

Total amount to be paid is,

The price of the four pack is $3.40 . If the shopper buy a pack of 4, so he needs to but 6 of this as he needs 24 in total.

Total amount to be paid is,

Therefore, the best deal is the pack of 4.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
