Exercise 54 Page 604

The only unknown is the number of toppings. Everything else is known.

$2$

Practice makes perfect

We know that Gordon got

3

scoops of ice cream, for which he paid

$ 1.19

per scoop. We also know that each topping costs

$ 0.49 .

If we call the number of toppings

t,

we can write the following equation.

3 (1.19) + 0.49 t = 4.55

Let's solve for

t

in this equation.

3 (1.19) + 0.49 t = 4.55

Multiply

3.57 + 0.49 t = 4.55

$LHS - 3.57 = RHS - 3.57$

0.49 t = 0.98

$LHS / 0.49 = RHS / 0.49$

t = 2

The number of toppings is

2 .
