How Much Are The Cars?

Can Someone Help Me With This One? Thanks: Matthew Currently Has Enough Money To Buy 45 Toy Cars. If The Cost Of Each Car Was 10 Cents Less, Matthew Could Buy 5 More Cars. How Much Money Does Matthew Have To Spend On Toy Cars?

  • Answer:

    Let p be the price in cents. 45p = 50(p-10)    (left side is what he can do, right side is "what if" the price were lower. 50 cars is 5 more than 45 cars.) 45p = 50p - 500    (multiply it out) -5p = -500    (subtract 50p from both sides) p = 100    (divide both sides by -5) 45p = 4500    (this is the amount Matthew has, in cents) Matthew has $45.00 he can spend on cars.
