Question

An ice cream shop sells large cones for $2.50 and small cones for $1.50. Jack has enough money to buy 21 large cones. How many small cones could Jack buy?

Answer 1

Step-by-step explanation:

Cost of 1 large cone = $ 2.5

Cost of 21 large cones = Jack's total money = 2.5 × 21 = $ 52.5

No. of small cones that can be bought from $ 1.5 = 1 small cone

No. of small cones that can be bought from $ 1 = 1 / 1.5 small cone

No. of small cones that can be bought from $ 52.5 = 52.5 / 1.5 = 35 small cones

With the money Jack has , either he can buy 21 large cones or 35 small cones .

I hope it helps you. If you have any doubts, then don't hesitate to ask.

Answer 2

GIVEN :-

• large cones cost $ 2.50

• small cones cost $ 1.50

• jack can buy 21 large cones

TO FIND :-

• how many small cones jack could buy

SOLUTION :-

now we know ,

jack have money to buy 21 large cones

$\implies \rm{total \: money = 21 \times price \: of \: large \: cone}$

$\implies \rm{total \: money = 21 \times 2.50}$

$\implies \rm{ \bf \: total \: money = 52.5 \: \ }$

now we know total money jack have

$\implies \rm{no \: of \: small \: cones = \dfrac{ 52.5 }{1.50}}$

$\implies \boxed{\rm{no \: of \: small \: cones = 35}}$
